From the Language & Font menu, selecting International Fonts, the only available language is English. I noticed that blender-2.37-dirs.patch makes blender look for the .Blanguages file in a different path from where the ebuild installs it, and changing the patch accordingly solved the problem. I suppose the problem affects the previous versions too, so I'll attach the corrected patch.
Created attachment 169202 [details, diff] corrected patch.
Simone, the patch seems to remove the capability for users to have their own internationalization data. I'm not sure if it would be possible to allow both?

Perhaps a solution would be to remove that patch and make /usr/bin/blender a script that checks for the presence of .blender/ in the user's home directory, copies the data there if it's not present and runs the binary. I just made the smallest change that makes blender's internationalization work out-of-the-box.
thanks for the report and patch, the patch/path is fixed in cvs.
