Description:
I was trying to rebuild ktechlab. At the first shot the build fails because the PKGBUILD doesn't source the qt3 profile, I fixed it (on trunk too). Then, again, the build fails with this message:

I googled a bit, but I found nothing. Gentoo/Fedora removed this pacakge, maybe we should just remove it too.

Additional info:
* ktechlab 0.3.7-2

Steps to reproduce:
Try to build it from trunk
