Bugzilla Bug 192895

I did a new bootstrap from stage 1 under amd64. Then I tried to emerge -e
system and it failed on busybox. Error message was:

Seems that emerge -e system wanted to emerge busybox before pam, even though
busybox has IUSE=pam. Emerging pam then emerging busybox solved this error, but
maybe portage couldn't do it on its own?

Reproducible: Always

Actual Results:  
emerge -e system failed on busybox because pam was not emerged before.

Expected Results:  
emerge -e system goes well :)

I think there should be the following added to the busybox ebuild:

DEPEND="pam? ( sys-libs/pam )"

fixed in cvs, cheers
