I accidentially introduced a circular dependency in my first interaction
with MesaLib :-)
I use the gnuplot backend already, I've had problems with the gl backend
probably because I'm using old nouveau as a driver and it supports a lot
less fancy OpenGL stuff.
The biggest issue for me with octave from pkgsrc is that I don't seem to
be able to install packages from octave forge, I haven't figured out why.
I should investigate more / open a bug report for it.
I'm not a heavier user so I didn't notice the absence of optimizations,
but I bet people who are would appreciate it a lot! worse performance
seems to be the biggest complaint about Octave.
I've used Octave a lot and prefer it, but I haven't given MATLAB an
honest try - it was "develop on own machine, using favourite editor
and comfortable OS, possibly at home" vs. a library Windows machine.
(I didn't try to get a license)
