Chris,

thanks for the response.  You nailed it on the head.  (Unfortunately I
burned a couple of hours figuring that out myself... I should have
procrastinated for a while on this issue.)

I have a pre-release of trinity desktop environment R14.0 installed,
and for some reason I will look into next, it installs another sip
package which is incompatible with PyQt.  I've had trinity installed
for over two months with no issues, which I guess shows how little
python I use.

Since I never saw this until I tried FreeCAD, I incorrectly pointed my
finger in FreeCAD's direction.  Apologies to all concerned.
