Changes (by kosmikus):
* milestone: cabal-install-0.14 => cabal-install-0.16
Comment:
This is still present with the topdown solver, but the modular solver
handles it ok:
{{{
$ cabal install base-4.5.0.0
Resolving dependencies...
cabal: Could not resolve dependencies:
next goal: base (user goal)
rejecting: base-3.0.3.2, 3.0.3.1 (global constraint requires ==4.5.0.0)
rejecting: base-4.5.0.0 (only already installed instances can be used)
rejecting: base-4.4.1.0, 4.4.0.0, 4.3.1.0/installed-20f..., 4.3.1.0,
4.3.0.0,
4.2.0.2, 4.2.0.1, 4.2.0.0, 4.1.0.0, 4.0.0.0 (global constraint requires
==4.5.0.0)
}}}
There's still an issue here to figure out a sensible way to specify non-
upgradeable packages per compiler.
