Sage fails to build under Darwin 10 (Mac OS X "Snow Leopard") because
of a few small bugs in several of the packages. Here are the fixes,
sorry if someone has posted these before, but it would be nice if the
3.4.1 tarball built out of the box :)
It still won't finish building, but the remaining issues are more in-
depth (if you want to actually fix them – you can hack around them by
editing system headers) and they are probably solved in later python
releases, so I might leave them alone and wait for someone to update
the included python if there are plans to do so soon. If not, tell me,
and I can hack something together by Wednesday. I thought I'd post
what I have, so here it is:
1) readline has issues detecting the OS. This is a known problem and
was fixed a while ago, but sage uses an old version. Here's a simple
fix (assuming you're in the sage-3.4.1 directory):
cd spkg/standard
tar xf readline-5.2.p6.spkg
cd readline-5.2.p6
sed -i "" -e "s/== '9'/-ge '9'/g" spkg-install
cd ..
rm readline-5.2.p6.spkg
tar cjf readline-5.2.p6.spkg readline-5.2.p6
rm -rf readline-5.2.p6
2) GMP's config.guess fails to run its piece of assembly code to auto-
detect the CPU type because of some architectural issues (I think cc
is trying to link a multi-architecture object against a single
architecture object, failing silently, and declaring the CPU 32-bit
only). Again, from the sage-3.4.1 directory:
cd spkg/standard
tar xf gmp-mpir-1.1.spkg
patch -p0
--- gmp-mpir-1.1/src/config.guess
+++ gmp-mpir-1.1/src/config.guess

3) -Wno-long-double isn't an option in Snow Leopard's cc.
cd spkg/standard
tar xf python-2.5.2.p9.spkg
