Hey, Bruce!! It will be difficult to tell what is actually wrong without
a copy of your header file, but I'll try my best here.

This looks like is_user needs to be linked against libdl.a, just include 
a "-ldl" in the linking commandline. Probably the best way to do that is
to add that to the end of the LDFLAGS variable in your header file.

Your header file should have something similar to the following in it:

XCFLAGS             = -D_NO_PROTO
XLDFLAGS            =
XINCPATH            =
XMINCPATH           = -I/usr/dt/include
XLIBPATH            = -L/usr/openwin/lib
XTLIBPATH           = -L/usr/openwin/lib
XMLIBPATH           = -L/usr/dt/lib
XLIB                = -lX11
XTLIB               = -lXt
XMLIB               = -lXm
XEXTRALIBS          =

Once you make these changes, you should be able to try all of these
programs again by editing the necessary list files and running
gmake again...

If you are still having problems, I can send you my header file
which I used to get a stable build of XGrass on (which includes 
xzoom)... I haven't touched MAPGEN, though....
