Bugzilla Bug 136303

valgrind and callgrind where separate packages before valgrind-3.2.0. In this
release, both packages where merged (see ChangeLog of valgrind). Therefore, if
valgrind is merged without removing callgrind ...

$> equery belongs /usr/include/valgrind/callgrind.h
[ Searching for file(s) /usr/include/valgrind/callgrind.h in *... ]
dev-util/valgrind-3.2.0 (/usr/include/valgrind/callgrind.h)
dev-util/callgrind-0.10.1-r1 (/usr/include/valgrind/callgrind.h)

Suggested solution: block update from 3.1.x to 3.2 if callgrind-* is installed
as well.

Additional information: 
KCachegrind, a graphical frontend for callgrind (part of kde-base/kdesdk),
implicitly depends on dev-util/callgrind as a package on its own. Therefore,
kde-base/kdesdk tries to re-merge callgrind-0.10.1 when valgrind-3.2.0 was
installed.

Note: there's a separate(?) ebuild for kcachegrind as well that explicitly
depends on dev-util/callgrind.

KDE people, could you please take care of the changes in kcachegrind and
kdesdk?

It should depend on either callgrind or >=valgrind-3.2.0

And I think that the x86-only dependency in both ebuilds can now be a "x86 ppc
amd64" dependency instead, because valgrind is no longer x86 only. 
Changelog entry for reference:

  25 Jan 2003; Caleb Tennis <caleb@gentoo.org> kdesdk-3.2.0_rc1:
  Make calltree dep an x86 only dep as it's for valgrind is which for x86 only.

Oh, I forgot to mention. Valgrind-3.2.0 now blocks on callgrind, as it should.

When I try to install callgrind, I get following:

checking for valgrind version... valgrind-3.2.0
configure: error: Unsupported version. This tool is for Valgrind 3.0.x/3.1.x

Calculating dependencies... done!

Thanks, I fixed this in both meta and monolithic:

Samuli, your issue should now be solved as well. I initially forgot to fix
callgrind's deps.

Thanks.
