Hi Jim,

Can you do

file /usr/local/lib/libzmq.1.dylib


file `which ruby`

Could it be that ruby and libzmq were compiled for different architectures?

I have downloaded the latest zeromq stable version, ran ./configure, make and make install. By default it installed to /usr/local. Now I am attempting to install the zeromq Ruby language binding but cannot get it to find my zeromq installation. I have tried several things, but the following 2 are the ones that should work but don't:
