Comment:
@Piraty you may want to include this script and place it it /etc/profile.d/, it defines a number of environment variables necessary to run the Draw program: https://git.archlinux.org/svntogit/community.git/tree/trunk/opencascade.sh?h=packages/opencascade

Additionally, this update causes a segfault in freecad. when loading any file (or switching to any workbench). I'll see whether rebuilding freecad will fix this.

But, it does build and run on my box: x64, glibc.
