On our university's Solaris systems, users have to set a library path
to get some software running correctly. Though I sometimes had the
impression that LD_LIBRARY_PATH didn't work as expected on Linux systems.
In Debian system, the LD_LIBRARY_PATH doesn't seem to be used much
though we do make use of preload path.

Implementing these would close the bug.
