I thought ATLAS would build! I believe if you should be able to get up 
to the point where the  sage-4.1.1.spkg gets going. I think the 
installation will fail there due to two separate bugs.

At least now the impact of not fully tuning the ATLAS code will only be 
seen on sun4v machines, not all of them. Perhaps you can review the 
atlas patch, which is about as simple as they go.

Since polybori-0.5rc.p9 built for you, perhaps you can look at:
http://sagetrac.org/sage_trac/ticket/6437

Perhaps you could try the revised MPFR patch,
http://sagetrac.org/sage_trac/ticket/6453
Note however, the version of gcc you used (4.2.4), did not actually 
exhibit the problem, which is why I changed the default gcc. But I have 
confirmed it passes with the latest gcc now.

It is NOT a bug in gcc 4.4.0, but Sun have admitted this is a bug in 
Solaris. The fix allows MPFR to build on any machine, with any version 
of gcc and pass all tests with no impact on performance except on sun4v 
machines.

I noticed my patch to singular worked for you
http://sagetrac.org/sage_trac/ticket/6563
There is probably a better solution than that one. The singular 
installation appears to be broken by a patch added to Sage to 
patches/kernel.Makefile.in.diff.

I don't know if you can shed any light onto what that patch was supposed 
to fix, as it seems have changed 'cp' for the 'install-sh' program and 
broke the installation in the process.

I seem to be slacking at the minute, as there are only 4 Solaris patches 
needing review!!
