Hi ports + steven,
So I went to use the glpk module for ocatve today to find that glpk was
not compiled in.
Infact, glpk support does get compiled in *if* glpk happens to be
installed at the time of build.
The obvious thing to do is (sadly, this does not work, read on):

However, this results in a runtime linkage error:
...

This is a known error with older versions of ocatve:

Our version of octave is ancient. Is anyone working on an update? If
not, I am going to have a go, because I want to use this feature.
Until then, I propose:
