It just means you will need Open Motif installed.  Most of the Linux distributions have these libraries available through apt, yum, or whatever.  There is a FreeBSD port as well.  This should just be noted in the install documentation for the convenience of new users.

The practice of statically linking in a Motif library should have died with SunOS 4.

-ljpeg, -lpng, -lXmu, and -lXft to get these dependent libraries linked
in.  This wasn't required before for 10.3, but it is now.  But from what
I can tell, these dependencies were already in the 2010-01 binaries I
built using openSuSE 10.3.  Now I have to be explicit about this.

For the maintainers of the various Linux distributions of cmucl, can I
just add these libraries explicitly?  Will that cause a problem?
