HPUX 11.11 DBI, DBD, Pg ld: Mismatched ABI (not an ELF file) for -lpq, postgresql

Hello,

Is there anyone out there who can help me ?

I'm trying to write a tiny little perl script to fire data into a
postgres database from a couple of HP-UX 11i boxes.
I need to install either DBI & DBD or Pg.

I follow the instructions exporting the Library path & the include path
for Postgres but no matter which way I go there's always a failure
building either Pg or DBD. I'm assuming it's to do with libpq.so which
does not seem to have gotten installed anywhere. I've looked all over
the place for this .so but cannot find it.

The error I get is:
