so what's the architecture of pix_demo.pd_darwin, Gem.pd_darwin and Pd
resp.?

most likely you are using an i386 Gem (as provided on gem.iem.at) and
Pd, so you need to make sure that your external is i386 as well.
do this by passing "-arch i386" (or even better. "-arch i386 -arch
x86_64", which will give you fat binaries) to both the compiler and the
linker.

if you build pix_demo in-tree (that is, in extra/, like pix_drum)  using
Gem's build-system, this should happen automatically via the
@GEM_ARCH_CXXFLAGS@/@GEM_ARCH_LDFLAGS@ templates.
