Can anyone shed some light on what this message means:

`gtk-config --libs`

This program ('pixmap') is from the examples which ship with gtk+-1.2.1.
(/usr/pkgsrc/x11/gtk/work/gtk-+-1.2.1/examples/pixmap).  I just added the
'-g' to the Makefile.
This is on a NetBSD-1.3.3 DECstation 5000/200.
I'm logged in remotely from a different NetBSD machine (mac68k) and have
the DISPLAY set to the mac.  If I try it the other way around, ie build
the program on the mac, sit at the pmax, remote log into the mac with the
display set back to the pmax, then the same program (which is now
executing on the mac and displaying on the pmax) causes the pmax X server
to crash.  Other combos of local/remote displays and machines are all
fine (solaris-sparc, solaris-x86, netbsd/mac68k).

I'm not able to take this machine down to try 1.4 right now as its in
continual use.
