Bugzilla Bug 67564

APG version 2.3.0b has optional compile time support for cracklib, but the
current apg-2.3.0b.ebuild does not use it.  From apg's man page "-k    check 
every  generated password using cracklib. To use this ability you must enable
cracklib support during programm building."  So I created this ebuild to add a
USE flag for cracklib support in APG.  This is my first time doing anything w/
ebuilds, but this seemed like a fairly simple thing, and this ebuild works for
me.  If the USE flag is specified at emerge, it applies a patch to APG's
Makefile to enable the cracklib support.

Reproducible: Always
Steps to Reproduce:
apg -k
Actual Results:  
apg: unknown option -k

Expected Results:  
Generated passwords checked against cracklib to ensure strong passwords.

The one biggest thing I was unsure of was in my patched Makefile to enable
cracklib support one of the envirement variables required is CRACKLIB_DICTPATH,
which should be whatever DICTPATH was when cracklib was installed.  In
cracklib-2.7-r10 this was "/usr/lib/cracklib_dict".  I wasn't sure if there was
any way to check for any other possible DICTPATH at compile time (or even if it
would be necessary to), so I just hardcoded it to "/usr/lib/cracklib_dict".

APG Makefile patch to enable cracklib support.

Goes in /usr/portage/app-admin/apg/files/

Oh, and I guess something like this should go into
/usr/portage/profiles/use.local.desc
app-admin/apg:cracklib - Support for cracklib strong password checking

Rob, I need help with this -- TaD's not with gentoo any more due to his real
life obligations.

thanks Conway, in portage.
