Following up on this message thread:

Installing VMD 1.9.1 in Ubuntu 14.04.1 LTS on an i386 laptop:

#1) Initial install from source ran VMD with initial error message:
"rlwrap: command not found". This was due to a non-installation of
rlwrap.

#2) Installed rlwrap. Now VMD refused to run; error message was "rlwrap:
No match." Checked vmd start script in /usr/local/bin/vmd; vmdprefixcmd
was set properly to read "rlwrap -C vmd -c -b(){}[],&^%#;|\\ -f
${MASTERVMDDIR}/vmd_completion.dat"

#3) Edited rlwrap command to eliminate word-breaking characters ie
"rlwrap -C vmd -c -f ${MASTERVMDDIR}/vmd_completion.dat"; vmd starts
normally

#4) Added in the word-breaking characters carefully testing each
addition. Final working command is "rlwrap -C vmd -c -b(){}],&^%#;|\\ -f
${MASTERVMDDIR}/vmd_completion.dat"

The problem with Ubuntu is two-fold. First, rlwrap is choking on the "["
character for some reason. Second, it only happens when csh is invoked.
The original rlwrap command (including [) works find in tcsh.

I haven't clarified whether this is an rlwrap bug or a csh bug in Ubuntu
14.04. The immediate solutions at the moment appear to be either editing
the "[" character out of rlwrap word-breaking characters or switching to
a different shell in the script, such as tcsh.
