Hi,

I configured a build farm and did some build testing and the list of
blockers is now actually a bit longer for 4.1.2:

The following is a FORTRAN issue.
   #6533         sage >= 4.1.rc1 doesn't build on cleo (ia64-Linux-rhel5)

Our itanium support is completely dead, since Sage doesn't build on
SUSE either due to the Maxima upgrade:
     #7113       Maxima does not build on SUSE Itanium (Iras)   blocker
        tbd     defect  doctest         --

There is still absolutely zero further progress since my last report
on OS X 10.6.  Nobody is working on this, but I hope to find time to
do so:
   #7095        os x 10.6 port -- numerous mysterious errors caused by weird
"abort trap" issue      blocker

Georg Weber reviewed this with many helpful comments.  I also tested
it on some systems and it works:
   #7021        [with patch; needs work] Update prereq from 0.3 to 0.4

This will be fixed by switching to the new notebook (which I hope to
do today).  Victor Miller found the "last" known bug in the new
separated notebook and I fixed it:
    #7060       notebook -- templating patch introduces numerous bugs
    #7080       include new separated sage notebook in Sage

On PPC OS X 10.4, Sage doesn't build at all for multiple reasons.
Either we fix this or deprecate PPC 10.4 support completely.  I think
deprecation is a fair option, since it's an OS that is 2 versions
behind:
     #7107      sage does not build on ppc os x 10.4 anymore, failing with mpfr
     #7115      building cliquer Cython extension fails on OS X 10.4 PPC
(with cliquer-1.2.p0.spkg)

There are differing reports on this.  I think it is just one bad
doctest, but Minh observes much worse trouble on the same machine (I
bet his environment vars are misconfigured):
     #7108      Sage 4.1.2.rc0 doctest failures on 32-bit Fedora 9 (cicero
on skynet)

I don't know anything about this except whoever wrote it (Robert
Miller?) should comment:
      #7111     timeout when doctesting partition refinement code

I haven't looked too closely, but there are tons of doctests failures
on OS X 10.5 PPC:
     #7112      os x 10.5 powerpc -- there are many many doctest failures all 
over


If anybody wants accounts on relevant computers to try to debug any of
these, please write to me.
Before working on any, be sure to check:
