This is line 600 of glpk.m, which is an Octave function that wraps the 
actual call to the GLPK library.

glpm.m is always present, even when Octave was built without the GLPK 
library.

No I don't think you can simply "add" GLPK.   If your version of Octave 
was built without it, it won't work.

What you need is both the GLPK library AND a version of Octave that was 
built with GLPK support enabled.

Yes, it usually is.  Do you know which particular OS is used on the 
cluster ?
