Currently wdm pamd file is using pam_stack module (which won't work with openpam) and the full path to the module (which breaks both on openpam and on no-lib32 amd64 systems). The attached patch applied over current ebuild and the wdm-include pamd file fixes the problems, using include directive and just the name of the module instead of the fullpath. I've also added dependency on virtual/pam (sys-libs/pam-0.78) as it's probably needed at runtime to have it working with pam. HTH, Diego
