[ITK] Fwd: ITK and python wrap problem

[Michka Popoff]

Please keep the discussion on the mailing list :)

Okay, so you will have to find the paths to the right folders/files to be consistent in your python choice.
I would be happy if you could communicate me the paths for Ubuntu 12.04, so I could extend the installation procedure.

Seems on ubuntu the procedure is the same for loading the shared libraries:

On Ubuntu you should have a /etc/ld.so.conf file. Then you should run ldconfig.
