Bugzilla Bug 166547

While I emerge crystalspace/crystalspace-1.0 the emerge freeze (loop ?) during
the recalculation of lightmaps.
The last lines of output :

crystalspace.engine.notify:
  Recalculation of lightmaps forced.
  Initializing lighting (24 meshes).
0%....10%....20%....30%....40%....50%....60%....70%....80%....90%....100%
  Shining lights (0 lights).
0%  Time taken: 0.0000 seconds.
  Caching lighting (24 meshes).
0%....10%....20%....30%....40%....50%....60%....70%....80%....90%....100%
Cleaning up...

And it is waiting (I have waited more than 1 hour with no change).

Reproducible: Always

Steps to Reproduce:
1.USE="cal3d cegui cg java javascript ode vorbis wxwindows" emerge crystalspace
2.
3.

I'm sorry for that. It did happen to me once, but I thought is just my messed
system, and I have to kill cslight manually to let the process continuing
ebuild. I repeated that and did not happen anymore. 
I think I will move that phase out, so you will have to do manually, but at
least it does not stop the emerge phase

Yes.
When I kill cslight when blocking, emerge continue without any problem.

Thanks

Fixed in portage. Instruction  to recompute are given during the emerge, but
they are not more automatically done
