libtool finding wrong version of library

[John Cartwright]

Hello All,

I'm using libtool 1.5.22 on a RHEL 5 64-bit system.  My problem is that 
libtool seems to be picking up an older 32-bit version of a library 
rather than the newer 64-bit version that I need.  I've tried putting 
the correct one first in the LD_LIBRARY_PATH, but that doesn't seem to 
help.  Can someone suggest a way that I can influence libtool's behavior 
on this? 

In the example below, I'd like libtool to use the libexpat.so from 
/extra/contrib/expat-2.0.1/lib rather than the one from 
/extra/contrib/oracle/product/10.2.0/db_1/lib.

Thanks!
