That's generally true for most programs, but crypto programs in
particular tend to be different.  Crypto very often contains
endian-specific code for performance reasons, and thus someone
building a fat binary needs to take care they don't end up with big
endian code on an Intel Mac, or little endian code on a PPC Mac.
GnuPG (at least 1.4.x) can be built "fat", and there are special
options in configure to handle the endianness issue (see the README
file).

Still, the original problem reported with libgpg-error-1.4 is not
related to building fat or not.  The package doesn't yet compile at
all.
