This last suggestion did not work for me.  I got the same undefined 
symbol error.  My linux setup is a 64 bits kernel running on sort of a 
hybrid 32/64 bits system.  By that I mean I have some 64 bits userland 
along with the 32bits.  When I configure python programs using the usual 
commands it comes back with arch x86_64.  Anyway I guess this is getting 
off topic for this list now, but suggestions are welcome nonetheless.
