I am using pam_krb5 and created a new ebuild for the actual release 3.10 on http://www.eyrie.org/~eagle/software/pam-krb5. I've (hopefully) "improved" the pam_krb5-3.9 ebuild by using the pam eclass and doing doc install with dodoc and doman dependig on USE="doc".
Created attachment 144663 [details]
... one more - of course I am already successfully using the ebuild myself ;)
Added to CVS, thanks mate ;)
