Thanks for the clarification regarding the glpk.m function.

For future reference, is there any reason why I would want to build
Octave without this support enabled?

The current OS is Ubuntu 14.04.5 LTS, Trusty Tahr. There is the option
to run the command: 'do-release-upgrade' to update to 16.04.6 LTS,
Xenial Xerus. As a result of my 'wonderful' experience updating to new
Windows versions on my own personal computer I have been hesitant to
do the same on the cluster.

Many thanks,
