well -- Octave one should work no-problem, with Matlab one (blame is
mine since I haven't had time to implement install-time building of
extensions and just distribute Mario's copies) we would need to figure
it out...

Mario -- you just staticly build-in GLEW, don't you?  so I could just
drop dependency on libglew altogether for that matlab- package, or
I have forgotten smth?

freenect -- would you mind rebuilding your extensions against freenect
0.2?  for some reason I have only uploaded 0.2 to Debian proper but not
to NeuroDebian, and now users on bleeding edge Ubuntu releases with
neuroDebian end up "bleeding".   Ella -- I will push a build of 0.1
version of libfreenect for trusty tomorrow to NeuroDebian so we would
have a quick resolution for that one at least...
