Hi Zac,

The above is a good thing to do first.  I suspect that you'll get "not
found" for libaqsistex.so.  It's probably not a bad idea to get a useful
error message by hacking aqsistypes/plugins.cpp:DLOpen() to include
something like the lines

if(!handle)
  Aqsis::log() << error << "Could not load plugin: \"" << DLError() << "\"\n";

If you find that libaqsistex.so is not found, the quick and dirty
solution is to add (DY)LD_LIBRARY_PATH, although there's a way to do it
properly with a compile-time "rpath".  I don't remember the details of
the rpath stuff atm.

Here's a little test project I cooked up (partly since I was curious how
to use dlopen() in general).  It has all the basic features of your
problem, and the DSO fails to load when "libhello.so" isn't in the
linker path, as expected.
