yes... but for octave I do build actual binary packages on every
Debian/Ubuntu release and specific libglewVERSION dependency gets
automatically inserted (I just build-depend on libglew-dev).  For
matlab, since I just take your binaries atm, I didn't bother building
per-release binary package but make the same package available, thus
hardcoding those dependencies.

;-)  yeap... and as a quick workaround for original problem I now
uploaded a backport build for 14.04 as well (the same for freenect
0.1), so issue should be resolved (tested in a clean 14.04 environment
-- installs fine now, just do apt-get update first)

They will, if neuroDebian repository would be enabled.  since we do not
support carrying multiple versions of packages atm, and we do not have
automated migration machinery (such as unstable->testing in Debian) I do
not want to upload 0.2 to NeuroDebian "proper".  I did upload it for now
(few 32bit builds still TODO), to NeuroDebian -devel (let me know if you
need instructions) so you could install/build against it and then we
would upload both upcoming PTB-3 and freenect 0.2 to NeuroDebian for all
Debian/Ubuntu's.

once again, for now I just uploaded 0.1 backport for 14.04 -- it should
not cause any trouble I believe and should resolve the issue.
