I have worked most recently with the medm2-3-4a source.  I have not run
into problems with missing directories so maybe you got a bad
distribution file.

For the other problems I have never experienced a problem with the
missing osfXK_Left and such.  I wonder since you find XK_Left if you
have Motif installed on your system.  This is not a standard part of the
Linux distribution.  Since OSF licenses Motif it will typically cost
money for a license ($100-150US).  I am using Redhat's Motif although
most versions probably work.  If you do have Motif installed, do you
have the directories set up properly in the CONFIG_***** files.

The XrtGraph stub file should be placed in the
/usr/local/epics/extensions/source/medm/medm (or equiv) directory.  This
simply sets up call stubs for the XRTGraph portion of the code.  This is
used with the cartesian plots.  XrtGraph is also a comercial package but
has typically costed quite a bit.  One nice thing w/ many of the Motif's
available on Linux you get a copy of the XRT development kit.  This
means that you can actually get the cartesian plots as well.  Note that
if you go the stub route,  I had found a few minor bugs in this that
kept me from compiling until they were fixed.  I think that I sent
something to tech talk a while back on this so check the archives if you
run into problems here.

For reference, I am using RedHat Linux.  I have compiled many versions
medm on many diferent kernals of Linux (RH 4.1-RH5.1) so this really
should not cause much trouble.  

Hope this helps some,
