Comment (by SerpentChris):

 Update: I tried downloading the pyzmq source code off github, and
 compiling it that way. The problem is that when it tests the installed
 library, it compiles a C file into an executable, but when I run the
 executable it says "Illegal Instruction" and exits with code 132. I don't
 fully understand why it takes two steps to build the executable though.
 Here are the lines:

 {{{
 /usr/bin/gcc-4.2 -fno-strict-aliasing -Wsign-compare -fno-common -dynamic
 -DNDEBUG -g -fwrapv -O3 -Wall -pipe -Os -arch ppc -I/opt/local/include
 -Izmq/utils -Izmq/backend/cython -Izmq/devices -c buildutils/vers.c -o
 vers.o
 /usr/bin/gcc-4.2 -arch ppc -undefined dynamic_lookup -Wl,-rpath
 -Wl,/opt/local/lib vers.o -L/opt/local/lib -lzmq -o vers
 }}}

 I tried making my own very similar C program and running it and I got the
 same error. Here are the contents:

 {{{
 #include <stdio.h>
 #include <zmq.h>

 int
 main(int argc, char *argv[])
 {
   int major, minor, patch;
   zmq_version(&major, &minor, &patch);
   printf("Current ZMQ version is %d.%d.%d\n", major, minor, patch);
   return 0;
 }
 }}}

 I compiled this:
 {{{
 gcc-4.2 -I/opt/local/include -L/opt/local/lib -lzmq zmq_vers.c -o zmq_vers
 }}}

 I ran the resulting executable and got the same error, Illegal
 Instruction. This is all on my Power Mac G5 running OS X 10.5.8 btw.
