Comment:
This is a known issue. It's a limitation of the current cabal-install
dependency solver. It's not that it's taking the information from the
wrong place, but as a simplifying assumption it assumes that if the
versions are the same, they are the same. cabal-install will pick the
installed instance rather than the source instance if its dependencies
fall within the ranges that the solver determines are ok. In this case
that doesn't happen because its got different dependencies.
The current solution is indeed to bump the version.
The current dev version of cabal-install has a way to ask explicitly to
use the installed instance, ignoring the installed instance. Additionally,
the new cabal-install solver will probably do a better job in cases like
these. It considers each installed and source instances separately.
