In AIX 5.3, expat shouldn't be a shared library. The RPM that IBM provides as 
part of their "IBM LInux Applications for POWER" kit uses /usr/lib/libexpat.a 
which is a symlink to /opt/freeware/lib/libexpat.a. Did it come from the Bull 
Freeware archive? What TL and SP level are you running?

Can you do a lslpp -w /usr/lib/libexpat.so to see if some installp fileset 
installed it?

If only selected users are going to use certain applications, you could set up  
/etc/security/environ so that those users get a custom LIBPATH instead of 
setting a global one.
