The attached patch applied over current ebuild, if the new pam eclass is in place (see bug #93118), allows poppassd_ceti to work with openpam implementantion and fixes the problem of fullpath for amd64 (no-lib32 profile). It uses pamd_mimic_system function to create the base pamd file and adds cracklib support directly from the ebuild itself, so no more pamd file needed. HTH, Diego

Your patch didn't work quite right, creating a file called auth in /etc/pam.d/. I corrected that, and it seems to work just fine now, committed as poppassd_ceti-1.8.5-r1.
