You must run Motif applications in an environment in which the value of the XUSERFILESEARCHPATH environment variable includes the
app-defaults/MLWorks-mono
file distributed with MLWorks.
The following commands work in the bash shell. Replace <MLWorks> with the directory in which you installed MLWorks:
XUSERFILESEARCHPATH=<MLWorks>/lib/X11/app- defaults/%N%C:$XUSERFILESEARCHPATH export XUSERFILESEARCHPATH
