A few month's back, and a few moments before almost throwing my
Powerbook out the window, I enabled the root account, as officially
described (http://docs.info.apple.com/article.html?artnum=106290):
How to enable the root user
Mac OS X 10.5 or later
1. From the Finder's Go menu, choose Utilities.
2. Open Directory Utility.
3. Click the lock in the Directory Utility window.
4. Enter an administrator account name and password, then click OK.
5. Choose Enable Root User from the Edit menu
6. Enter the root password you wish to use in both the Password and
Verify fields, then click OK.
Mac OS X 10.4.x or earlier
1. Click the Finder icon in the Dock.
2. From the Go menu, choose Applications.
3. Open the Utilities folder.
4. Open the NetInfo Manager utility.
5. Click the lock in the NetInfo Manager window.
6. Enter an administrator account name and password, then click OK.
7. For Mac OS X 10.2 and later, choose Enable Root User from the
Security menu.
8. For Mac OS X 10.0 and 10.1, choose Security from the Domain menu,
then Enable Root User from the submenu.
9. If you have not previously set a root password, an alert box may
appear that says "NetInfo Error," indicating that the password is blank.
Click OK.
10. Enter the root password you wish to use and click Set.
11. Enter the password again for verification and click Verify.
12. Click the lock again to prevent changes.
Why working with sudo is safer than working as root is not clear to me.
After all, the danger is not in root but in the uneducated user. If
you're paranoid, you can keep using sudo until you get stuck and then
switch to root.

1. I was sourcing /sw/bin/init.csh, so that wasn't the problem...but:
2. I did find the problem (at least for the precompiled version from UC
Santa Cruz): For some reason "sudo ccp4i" gave the error message, but
just "ccp4i" (without the sudo) worked OK. (Although I thought the
first time you launched ccp4i you were supposed to do it using
sudo...??). Anyway, I'm good (although peeved at my continuing
inability to master sudo. I miss living on the edge with root).
3. I didn't try to debug the binaries I got from the ccp4 site, since I
now have a working package. However, Iain Kerr kindly provided this
info, which may prove useful to other small brains out there:
ccp4.setup is in ccp4-6.0.2/bin...it used to be in include..is that
your problem ?
Also, there's no ccp4i folder....the ccp4i binary is in bin/ also.
Note to the long-suffering folks at the secret underground world
headquarters of ccp4: Small brain or no, I spent a lot of time looking
around for some clue as to how to complete the install for the ccp4
package, to no avail; a README file to accompany the installer would not
be unwelcome...
Thanks,
Pat

You need to run
source /sw/bin/init.sh
if you use bash or zsh
or
source /sw/bin/init.csh
if you use tcsh.
this will automatically set up the environment variables and then it
will do what you want it to (which is to set up the ccp4 environment
according to whichever shell you might be using).

1. I tried to install Bill Scott's precompiled ccp4 on an intel mac
running OS X 10.5. When attempting launch ccp4i, I receive this
error message:
/sw/share/xtal/ccp4-6.0.2/ccp4i/bin/ccp4i: line 4 /bltwish: no such
file or directory
Typing "which bltwish" returns /sw/bin/bltwish, which jibes with the
definition of $CCP4I_TCLTK, so I'm not sure where the problem is...
2. Pfui. So next I tried jettisoning the apt-get installation, and
instead used the installer downloaded from the ccp4 site
(ccp4-6.0.2-osx-i386.dmg.gz). This goes swimmingly, until I actually
try to do something. Commands like "ccp4i" or "mtzdump" aren't
recognized, so I go looking for the ccp4.setup file; but it's not
there. Huh? Also, there's no folder named ccp4i, even though this
install is supposed to include it...
It's Friday, and I'm at the nadir of my weekly brain function, so
perhaps some kind soul will tell me where I'm going astray.
Thanks,
Pat
