Bugzilla Bug 164678

emerge --depclean wants to remove needed package (dev-php5/jargon in this case)
in 2.1.1-r2 (stable) and 2.1.2-r5 (~amd64):

$ equery d dev-php5/jargon
[ Searching for packages depending on dev-php5/jargon... ]
dev-php5/creole-1.1.0
$ equery d dev-php5/creole
[ Searching for packages depending on dev-php5/creole... ]
dev-php5/propel-runtime-1.2.0
dev-php5/jargon-1.1.0
$ equery d dev-php5/propel-runtime
[ Searching for packages depending on dev-php5/propel-runtime... ]
dev-php5/propel-1.2.0
$ grep propel /var/lib/portage/world
dev-php5/propel

Note: 
1. none of the packages is in package.provided -- I don't have one.
2. none of the mentioned packages use USE flags.
3. Both dev-php5/jargon and dev-php5/propel have RDEPEND on dev-php5/creole.
4. I use metadata_overlay (unset metadata-transfer in FEATURES) to cut down
sync time. I don't see why it should affect the portage behavior, as equery
finds all the dependencies just fine.

equery is known to be buggy for that type of query.  Please attach output from
portage-2.1.2-r5 for `emerge --debug --pretend --depclean`.

dev-php5/propel doesn't depend on dev-php5/jargon at all... neither does
dev-php5/creole -> equery d produces nonsense.

# emerge -pv dev-php5/propel

These are the packages that would be merged, in order:

Try w/ latest ~arch gentoolkit; the results you've posted are bogus.

http://sources.gentoo.org/viewcvs.py/gentoo-x86/dev-php5/creole/creole-1.1.0.ebuild?r1=1.1&r2=1.2

equery uses the ebuild in /var/db/pkg. portage/emerge uses the ebuild in the
live tree ($PORTDIR). creole no longer depends on jargon in the live tree. If
you need jargon add it to your world file.

Well, this is the output of the new equery (gentoolkit-0.2.3_pre3)

$ equery d dev-php5/jargon
[ Searching for packages depending on dev-php5/jargon... ]
dev-php5/creole-1.1.0 (>=dev-php5/jargon-1.1.0)

I can confirm dev-php5/jargon is not listed/mentioned as a dependency in emerge
-dp --depclean for portage 2.1.2-r5 (I prefer not to post the output if
possible)

I'm sure dev-php5/jargon was pulled down as a dependency when emerging propel,
this is the relevant part of the genlop output:

     Thu Sep 28 10:30:31 2006 >>> dev-php/PEAR-PEAR-1.4.11
     Thu Sep 28 10:34:02 2006 >>> dev-php5/phing-2.2.0
     Thu Sep 28 10:34:15 2006 >>> dev-php5/propel-generator-1.2.0

     Thu Sep 28 10:35:00 2006 >>> dev-php5/propel-1.2.0

comment #3 makes sense. Thanks.
