There seems to be a great deal of difficulty (brlcad, opencascade) in getting any of the open source CAD programs incorporated into the Linux distributions that maintain high standards on acceptable license terms and packaging guidelines (Fedora). Luckily, for a pragmatic guy like me I can now install FreeCAD from the RPMFusion non-free repos.
yum install freecad
I'm excited to see if I can get better Boolean operation results (less manual mesh fixing) with FreeCAD for 3D printing than I've had with Blender.
