Yes, on HPUX I think you probably have to do this. We build the
executables with SHLIB_PATH disabled, so even if pg_regress knew to
set SHLIB_PATH (which it does not) the programs would not seek for
shared libraries in the temporary installation, only in the configured
final location. I think you were probably picking up an older version
of plpgsql.sl that you hadn't yet overwritten by "make install".
