Compiling Molscript

["Raymond C. Fort Jr." <rcfort/at/maine.edu>]

 Apologies if this is a bit off topic:  I have been trying to compile
 Molscript under Linux (red Hat 6.2 or 7.2).  I have fought through most
 of
 the problems with location and names of libraries (with the help of
 makefiles  from Pierre Cotney and Edward Berry), but now I get the
 following error messages:
               -L/usr/X11R6/lib -lglut -lGLU -lGL -lXmu -lXext -lX11
 -ljpeg -lpng -lgd -lz -lm

 collect2: ld returned 1 exit status
 make: *** [molscript] Error 1
Has anyone successfully completed this task who would be willing to
 share a
 makefile?
Again, apologies to those who might consider this off topic, and
 thanks in
 advance for any help!
