As specified by Jean-Marc, toolboxes are loaded at runtime. Maybe you
should have a look at http://robotflow.sourceforge.net. This is a
robotics toolkit for Overflow. You should mostly see what's in the 
.../src/Makefile.am which contains the commands to automatically
install the newly created libraries into the proper directory.

That's what we do, but we are looking for .tlb (which are symbolic
links to .so files).

Good luck,
