Building pgeasy on HP-UX

Anyone know how to properly build pgeasy on HP-UX?  It used to build
seamlessly as part of pgsql.  The build doc is pretty sparse.


# gmake
...
cc libpgeasy.o halt.o -L/opt/pgsql/installs/postgresql-7.3.2/lib -lpq -fpic
-shared -Wl,-x,-soname,libpgeasy.so.3
-Wl,-rpath,/opt/pgsql/installs/postgresql-7.3.2/lib -o libpgeasy.so.3.0
