Tom already pointed in the right direction: one of the modules was 
dynamically linked against the openSSL library, but this library could 
not be found at runtime. Why this is I don't know, as you state you 
have /usr/lib/libssl.dylib. Maybe the extension was linked against 
another libssl version?

There is lots of debug output you can make the dynamic loader produce, 
see "man dyld". Maybe this gives a clue?
