understand 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?

I have to hack a bit to get a working Python in Open Solaris.

I do have a working Python! But I don't know it is setup properly :(

If you don't accept CFLAGS set globally, why not?

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.)

I don't know. It just says it installed successfully :)

Let's go for it!
