Log Message:
libXaw on many X11 distributions is linked against libXpm.  The linker
should automatically pull in libXpm when -lXaw is given, but it doesn't
seem to work correctly on Darwin.  Modify the xglyph Makefile so that
we explicitly link in -lXpm when we link against -lXaw.  This should
fix the problem noted on Darwin in the bulk builds.  Bump the PKGREVISION
to 4.
