Why do you think so? I believe Python always passes absolute paths
to dlopen, so any path resolution dlopen might do should be irrelevant.
*If* you can get dlopen to look at directories outside sys.path,
that would be a serious problem. You can use ktrace to find out
what places it looks at.

Running the test suite should already exercise this code a lot.
You should run the test suite both in "working copy" mode, and
in "make install" mode; if you know how to produce a Mac installer,
testing it in such an installer ("framework mode"?) could also
be done.
