:) - I am working on it, but it will be tomorrow until I am done.

Yeah, I am aware of that, but I just build Python 2.5.2 and numpy 1.1.0
and expect for the borken ctypes all tests pass on x86-64 Solaris with
Sun Studio 12 in 64 bit mode. Unfortunately I do not have the SunPerf
lib installed for x86-64, so I will have to do the whole thing on Sparc
again before attempting to come up with a set of working flags. I have
an ATLAS+Lapack build on that box, but I used gfortran, so it won't be
any good in debugging this problem.

One more thing: Sin Phil wants to build a 64 bit version he ought to set
Notice .../lib/amd64/... since lib contains the 32 bit version of the
library and lib/amd64 the 64 bit version.
And for the SunPerf lib itself: There are a bunch of them on my Sparc box:
-bash-3.00$ find /usr/local/SunStudio12-200709/ -name "lib*perf*"
And the same applies here: the v9 is 64 bit while v8 and v7 are 32 bit.
Hope this helps. If anybody cares I can send my notes on the build
(including Python) to the list so that someone interested can stuff them
in the wiki. There seems to be no mention of Solaris on
I also send some build info on 64 bit OSX out a while ago and somebody
mentioned that those might also be well placed in the wiki.
