Thanks
Pacho, please take a look at tor-0.2.4.17_rc-r1.ebuild tor-0.2.5.1_alpha-r2.ebuild to see that I used the eclass as expected. I think I got it right.
Looks ok to me, strictly: pkg_postinst() { readme.gentoo_pkg_postinst } readme.gentoo.eclass exports a pkg_postinst function for doing that, but some people prefer to specify it directly -> it's up to you then :)
