You are not missing the point. :-)

There is already a way to solve the above problem.  In addition to the
current directory and the standard directories, Mono looks in all the
directries indicated in the LD_LIBRARY_PATH variable.

In my case, I *do* want my own library directory.  Thus, I have this line
in my .bashrc file:

LD_LIBRARY_PATH=/home/daniel/lib


Cheers,
Daniel.
