kuka_lwr_fri not compling anymore

Hi all,
I am having problems in compiling the kuka_lwr_fri on a fresh installation (but i believe is an orocos related problem)

I have groovy, and ros both from git and deb.
i sourced the env.sh

these are the error i get.
it seems that the problem is about the orogen.rb ruby file, that cannot find some dependency (require 'typelib'), so i would guess some path problem

(i have 3 of typelib.rb:
Cheers, Gianni
