I'm generally fine with Sage including everything.  The only issue
comes up when I need to use tools which are common on Ubuntu but which
need to execute in the Sage environment.

In particular, where I'm getting bitten hard is svn and git.  Neither
will run with sage's libgnutls.

I "almost" had it beat by doing everything without the Sage
environment which uses general Ubuntu tools until it came to the
Enthought suite's "ets" command... ets calls svn from its python which
is installed in sage.

I can install svn and git into sage (which isn't that bad) or I can
adjust the libraries.  That is riksy as the headers can also get out
of wack which then becomes a more serious "adjustment" as I should do
this prior to building Sage (headers could get outta wack also)

So, I get the reasons and I think it works well but this is a problem
for me and its gotten a little bit harder with the latest Ubuntu
distro.
