 linker looks only into libraries that are noted as dependencies. Don't you
 load the library already before? I think the test imports the acl.acl
 module first. What do you suggest I try?

 Okay, after some more research I realized that sharing symbols
 between multiple loadable modules is very tricky, almost infeasible
 if we want to be portable.

 So I've developed a different workaround and committed it to the
 branch.  Could you try and review it?

 (This specific issue took much more time than I expected, so I've not
 addressed other issues yet).

 BTW, while working on this, I also considered an option of
 consolidating multiple modules into a single loadable module (.so).
 And, unless I miss something, it seems very difficult if not
 impossible.  It would be very close to re-implementing the import
 mechanism of the Python interpreter, which would be very complicated
 and contain subtle corner cases, and I'm not even sure if we can
 reasonably achieve that only using the exposed API.
