Paul, 

OGRSpatialReference is linked into MapServer and used when the OGR link
is there.  We could look at some mechanism for exposing some of the
OGRSpatialReference capabilities to perl - they are already accessable
to
Python. 

We could make cases for it belonging in PROJ or not, but for the time
being
I don't expect it to happen. 

For your specific needs would it be adequate to have an external
executable
you could run to translate WKT into PROJ.4?  I could make you up such a
thing
pretty quickly.

Later,
