Thanks for the inputs on this problem. This fellow did find the problem and
correct it,
as you can read below...

Subject: FW: dynamic linker problems

I fixed the problem - the binary wasn't explicitly getting linked with the
Motif library, so I just had to add '-lXm' to the linker options. I still
have a couple of questions, though - why, if libXm wasn't showing up in the
output of 'dump -Lv', was it being listed in the output of 'ldd' on host1?
And why didn't the compile fail at the link stage?

Thanks to, Michael F Gordon, Anderson McCammont, Casper Dik,
Rahul Roy, and Ronald Loftin.

Suggestions included checking the LD_LIBRARY_PATH variable (which we did
to sending this to the list), running "dump -Lv <binary_name>", checking
MOTIF library patch levels, check symbols using nm, and checking that the
was linked with -lXm explicitly. This last one seemed to be the kicker.
