Description Jeroen Roovers (RETIRED) gentoo-dev 2015-04-17 04:52:36 UTC
There is no SLOT conflict to warn about when you call --buildpkgonly with two atoms that would *only* conflict if --buildpkgonly was *not* issued.

# emerge -v1a =dev-db/mysql-{5.5.43,5.6.24} --buildpkgonly --nodeps

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

[ebuild  N    ~] dev-db/mysql-5.5.43  USE="community embedded extraengine perl ssl {test} -bindist (-cluster) -debug -jemalloc -latin1 -max-idx-128 -minimal -profiling (-selinux) -static -static-libs (-systemtap) (-tcmalloc)" 22,734 KiB
[ebuild  N    ~] dev-db/mysql-5.6.24  USE="community embedded extraengine perl ssl {test} (-cluster) -debug -jemalloc -latin1 -minimal -profiling (-selinux) -static -static-libs (-systemtap) (-tcmalloc)" 33,860 KiB

Total: 2 packages (2 new), Size of downloads: 56,594 KiB

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

  (dev-db/mysql-5.5.43:0/0::gentoo, ebuild scheduled for merge) pulled in by
    =dev-db/mysql-5.5.43 (Argument)
  (dev-db/mysql-5.6.24:0/0::gentoo, ebuild scheduled for merge) pulled in by
    =dev-db/mysql-5.6.24 (Argument)

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.
