How to include pgsql static libraries in your own app written in Xcode?

I am trying to write a plugin (for REALbasic) in C using Xcode on Mac OS X.
I have succeeded except that my plugin depends on dylibs that must be
installed on each client machine.

I'd like to create a plugin with all pgsql libs statically linked into my
plugin to create a standalone solution.

I've added the libpq.a library and included libpq-fe.h and postgres_ext.h
that it needs. The linker reports a bunch of errors:

"_BIO_free", referenced from:
_client_cert_cb in libpq.a(fe-secure.o)
_client_cert_cb in libpq.a(fe-secure.o)
_client_cert_cb in libpq.a(fe-secure.o)
_client_cert_cb in libpq.a(fe-secure.o)

etc...

I'm sure this is a straighfwd issue, but I have no idea what to try to fix
this and link in the libraries to my plugin.

Any pointers would be greatly appreciated,
Regards,
Peter.
