Evolution can't be removed without removing beagle. Since beagle should be
installable without evolution, it would make sense for evolution-sharp (which is
used to search contact details) to require e-d-s, not evolution.
here is the dependency chain in reverse - beagle requires evolution-sharp, which
requires libeshell.so.0 from evolution...
---> Package evolution.i386 0:2.6.0-1 set to be erased
--> Processing Dependency: libeshell.so.0 for package: evolution-sharp
---> Package evolution-sharp.i386 0:0.10.2-9 set to be erased
--> Processing Dependency: mono(evolution-sharp) = 184.108.40.206 for package: beagle
---> Package beagle.i386 0:0.2.3-4 set to be erased
evolution-sharp does not appear to need libeshell anymore, so I removed the
evolution-devel build requirement.
Fixed in evolution-sharp-0.12.2-2.fc7.
