start-script picks wrong yade libraries in ubuntu 14.04

[Bruno Chareyre]

If yade is compiled on 14.04 where yade stable is also installed, yade-mine executable will import the stable libraries present in /usr/lib/python2.7.
It makes it impossible to use compiled version (maybe also problems to expect if different binary packages are installed).

Took me a while to figure out the problem. The reason is the split of yade package into different subpackages I think. Not sure about best solution.
Should it be fixed on the packaging side or code side?

[Bruno Chareyre (bruno-chareyre)]

I think we should fix that quickly, else we will have a significant flux of weird bugs/questions from people who don't realize they are not running what they think they are running.
It will be extremely difficult for us (repliers) to understand the problems since, as shown above, the "Welcome to Yade VXXX" is showing an irrelevant VXXX.

Not clear to me: can we revert the current model where some yade modules are installed in standard python paths /usr/lib/python2.7/?
This is the easiest fix, but I'm not sure what are the constraints from the packaging point of view.

Should be fixed in 1722651fc.
Please, reopen, if it is not.
