Libraries (no matter if for FreeBSD or Linux) are searched in fixed  
locations (if they are linked into a binary the normal way). You can  
add other locations either globally by adding it to the ldconfig path  
(for linux it is a different setting than for FreeBSD binaries), or  
you can set the LD_LIBRARY_PATH variable to add the new location per  
program.

For FreeBSD see "man ldconfig" (for LD_LIBRARY_PATH, will be picked up  
by linux and FreeBSD, so don't set it globally but only for specific  
programs) and "man rc.conf" (for ldconfig_* variables which denote the  
global search path for FreeBSD).

For Linux I don't find the right global variable right now. We used to  
have one.

Unfortunately this doesn't give enough info about what's wrong.  
Someone would have to investigate with ktrace and/or DTrace.

Bye,
Alexander.
