ROS with Gentoo

Hello,
during my studies I had in different occasions to use ROS. I think it is 
a great tool but it bothers me that I am usually forced to use Ubuntu in 
order to have it working easily. In two previous attempts I tried to 
have it working on my gentoo workstations unsuccessfully. I am not sure 
if other people may have the same problem or not but in general I feel 
like there is not much information on how to run it on gentoo either 
because nobody is doing it or who has it working don't share the 
information.

I have now the basic system working and I would like to somehow document 
the little things that I had to solve step by step so that other people 
doesn't have to struggle with it or even for myself in the future. I 
thoguht on publishing it in wiki.gentoo.org but I wanted to ask first if 
it would be a good place. I would't be a full documentation of something 
stable but just a bunch modifications and steps that should be taken to 
compile the base system only tested on my system.

Thank you
Quim
