Bug 382823 – sys-apps/portage-2.1.10.11 : Put emerge packagename and emerge --depclean in coherency when resolving dependencies on multislotted packages

• Status: RESOLVED FIXED
• Product: Gentoo Linux

Following Bug 382721 I reported against nvidia-cuda-toolkit, I think it would be an enhancement of portage if emerge packagename and emerge --depclean were coherent when resolving dependencies.

exempli gratia :

- gcc-4.4.5 emerged with the multislot use flag.
- emerge packagename apparently considers that it fits for satisfying a build specifying a sys-devel/gcc:4.4 runtime dependency.
- But emerge --depclean apparently does not consider things identically and fails processing because :
-----------------------------------------------
* Dependencies could not be completely resolved due to
 * the following required packages not being installed:
 *
 *   sys-devel/gcc:4.4 pulled in by:
 *     dev-util/nvidia-cuda-toolkit-4.0
----------------------------------------

It would of course be simpler (on the user point of view) if both were considering that gcc-4.4.5 slot satisfies the dependency on a gcc-4.4 slot but if emerge --depclean must / can not be modified that way then emerge packagename should behave identically and should not consider that the dependency is satisfied too. 

Reproducible: Always
