It is nice to think that a binary installer could be built on 10.5 or
10.6 but I sure don't know how to do it.
I built the original installers using MACOSX_DEPLOYMENT_TARGET=10.4 and
gcc 4.0.1.
At your suggestion I built new universal unix libraries using
MACOSX_DEPLOYMENT_TARGET=10.3. As always, I deleted the dylibs so only
the static libraries remained (so they would be included in the final
binary) and I verified that the libraries contained both ppc and intel
code. I then used bdist_mpkg to build a matplotlib installer.
Unfortunately I see the same problem as before: when I try to import
pylab on a 10.3.9 PPC computer I get a segfault.
