The recommendation is to _not_ set the LD_LIBRARY_PATH.

Have a look at the search order of libs in linux. Correlate this with
the fact that when in linux an access is done to e.g. /lib/libX.so.y
which means that the linuxulator first looks
if /compat/linux/lib/libX.so.y is there, and if it isn't it looks
if /lib/libX.so.y is available.

AFAIR a work around is to add a link
in /compat/linux/usr/lib/librt.so.1 -> /lib/librt.so.1

I want to do something like this in the FC4 port, but hadn't time to do
it and test it so far.

Bye,
Alexander.
