805,Configure fails when AvailablePackage source is RepoTarballPackage,dmp,,"I'm having cabal configure will fail with

{{{
cabal: internal error: configure install plan should have exactly one local
ready package.
}}}

Checking the source code shows that this error occurs in {{{Configure.hs}}} when failing a pattern match in Configure.hs:88. The value that is coming back from {{{InstallPlan.ready}}} is in fact a list of one element, but it is failing on the {{{LocalUnpackedPackage}}} match. The value returned in my case has the value:

{{{
packageSource = RepoTarballPackage (Repo {repoKind = Left (RemoteRepo
{remoteRepoName = ""hackage.haskell.org"", remoteRepoURI =
http://hackage.haskell.org/packages/archive}), repoLocalDir =
""/Users/dave/.cabal/packages/hackage.haskell.org""})
}}}

This is happening for a cabal package which has a dependency on the binary package, but the binary package is not installed. It doesn't happen with all cabal packages, but just perhaps when binary is the only missing dependency. 

If I first run {{{cabal install binary}}} then the {{{cabal configure}}} will go through just fine. Unregistering the package  will again cause {{{cabal configure}}} to fail.
