so i emerged x11-libs/libfm-9999, then x11-misc/pcmanfm-1.1.0-r1 and then I try to downgrade x11-libs/libfm-1.1.0-r1 and I get this
helix ~ # emerge -1av =x11-libs/libfm-1.1.0-r1
These are the packages that would be merged, in order:
Calculating dependencies... done!

!!! Multiple package instances within a single package slot have been pulled

(x11-libs/libfm-9999::gentoo, installed) pulled in by
>=x11-libs/libfm-1.1.0:0/4.0.0= required by (x11-misc/pcmanfm-1.1.0-r1::gentoo, installed)
(x11-libs/libfm-1.1.0-r1::gentoo, ebuild scheduled for merge) pulled in by
I believe portage should allowed me to explicitly downgrade the library without marking the newest version first.
If we translate the argument into an implicit mask for the higher unmatching versions in the same slot, then that should solve it.

I would too like this behavior to be fixed.
