Are you sure that you need that?

On AIX, a *.a file may well be a shared library and can be used for
dynamic linking.

What is the result of "ar -t libphp5.a"?

When I LoadModule and point to the .a, I get:

root-at-backup:/usr/local/apache> bin/apachectl start

These don't look like shared objects, and it probably is really
a static library.

Gary explained it all elsewhere in this thread, and I can add nothing
meaningful to that.
