[Mike Frysinger]

does anyone recognize this off hand ?  ia64 stage3 builds are failing due to it.

 * Error: circular dependencies:

(sys-libs/pam-1.2.1-r2:0/0::gentoo, ebuild scheduled for merge) depends on
 (sys-libs/libcap-2.24-r2:0/0::gentoo, ebuild scheduled for merge) (buildtime)
  (virtual/pam-0-r1:0/0::gentoo, ebuild scheduled for merge) (buildtime)
   (sys-libs/pam-1.2.1-r2:0/0::gentoo, ebuild scheduled for merge) (runtime)

It might be possible to break this cycle
by applying the following change:
- sys-libs/pam-1.2.1-r2 (Change USE: -filecaps)

Note that this change can be reverted, once the package has been installed.
