I'd suspect an architecture mismatch or ABI mismatch. The "maci64" in the path suggests to me that libeng.dylib might be a 64-bit-only library while the framework path and the fact that the (presumably MacPorts-derived) Python you are using was built with gcc 4.0.1 suggests you are running on OS X 10.5 or 10.4 and the python installation is 32-bit only. That is easy enough to check: use `/usr/bin/file` and `/usr/bin/otool -L` on mlabramodule.so and lilbeng.dylib. -- Ned Deily, n...@acm.org -- http://mail.python.org/mailman/listinfo/python-list
