correctly, tries to use the flags that Python itself was built with). Just
setting CFLAGS directly can mess this up. Can you post the log of running
cython -f with this option? Also, Cython won't compile, do you have any
luck with all the .pyx files in the Sage library?

Yes. Worrying about Cython working before Python is set up correctly is
probably going to be an exercise in futility.

For fear of breaking things. I am not an expert on distutils or building
stuff, so for me the safest path is to not change stuff.

Do you get a working Cython with CFLAGS set? (If so, it might just be
lucky...) What errors do you get otherwise? (I think Cython's supposed to
fall back to a pure Python setup if the compile fails, but I could be
remembering wrong.)
> *.pyx files? I don't get sage-4.3.1.alpha build :)!
Yet :)
I'm just pointing out that whatever issues we're running into here, we'll
be running into later with the sage library.
> So let's get Python build correctly on Open Solaris x64!
Sounds like the best course of action.
