libzmq.dll needs to be in the PATH, try copying that file to Ruby\bin
or adding the directory where libzmq.dll lives to the PATH.

/usr/local or even /usr/local/lib are not in the PATH.

I haven't invested time in test latest version of zeromq to see why is all this.

Will try once I get home and let you know. At first seems to be that
the generated shared librari (dll) might not be compatible with the
FFI gem, but let's see.
