Something I meant to refer to earlier, it is considered bad etiquette to
cross post to multiple lists. It means in this case I have to remember
to drop the postgis list from my replies as I am not a member of that

Probably going to involve dealing with ldconfig.

Look in /etc/ld.so.conf and see if the directory that contains
libproj.so.12 is in there?
