Hmm, maybe that's the one that's being found when psql is started?
Seems like you need to look at exactly what search path is being
used (check LD_LIBRARY_PATH, /etc/ld.so.conf, or whatever controls
this on your system). Another possibility is that ldconfig needs
to be run again to update ld.so.cache.
