Colored man pages not working on gentoo

I have a problem using **these methods** to get colors in my man pages in gentoo. I've asked already in the gentoo forums but it still doesn't work, and the comments in a bug report (Bug 184604 ) don't work either. Can someone help me to get colours in my man pages? **EDIT**: Yes, I'm using less as pager and urxvt-unicode as terminal emulator **EDIT2**: I already asked in the gentoo forums but it didn't help, this is the link: http://forums.gentoo.org/viewtopic-t-819833-start-0.html .
