> Do you mean GCC-4.7.0 with GNU ld which is installed system-wide on mark
or do you mean a custom-built GCC-4.7.0 with Sun ld? Because building Sage
on mark with GNU ld never worked for me (at least `libpng` doesn't build).
The system-wide GCC 4.7.0 (which is configured to use GNU ld).
Unfortunately, with the default setup on the skynet machines
(`/usr/local/skynet_bash_profile`), the Sun linker comes first in `PATH`,
so some packages get confused, assuming the wrong linker.
E.g. to build libpng, you have to
{{{
#!sh
export LD=/usr/local/binutils-2.22/sparc-SunOS-ultrasparc3-gcc-4.6.2
-without-zlib/bin/ld
}}}

> I'm going to try building Sage on mark with GCC-4.7.2 (the optional
spkg) + Sun ld. If that works with this spkg, I think there is no reason
to hold up this ticket.
Yes. I was going to try that as well. (I'll open a ticket for building
Singular with GCC 4.7.x on Solaris soon; only needs a trivial patch to
`kernel/bigintmat.cc`.)
The odd IPython warnings (and/or making Python properly build `_ctypes` on
Solaris SPARC) should be fixed on another ticket.
Hopefully Sage 5.9.beta* gets out soon... ;-)
