Hi Nicolas, thanks for your support. I did all recommendations listed
INSTALL file inside /ors dir. That means that my blender is 2.6, my python
is also 2.6 and ACE is 5.6.3 I got ors file with bzr command from the
repository mentioned by Gilberto.
Hope I get it through to you!!!
Thanks a lot,
Breno
