Subject: Re: How to build Universal Binaries through Open Source code
Be very careful that nothing in the configure script is checking for
anything architecture-specific (like endian-ness). You may get bad
results on the architecture "opposite" your build machine's. For this
reason, I always go the route of building separate ppc and intel
versions (so that the configure script can make the correct decisions
for each architecture independently) and lipo-ing them together at the
end.
