Cabal install performs worse on Hugs

[Neil Mitchell]

Hi,

Using Cabal 1.4 Branch and Cabal-install HEAD:

C:\Neil\uniplate>cabal install --hugs
Resolving dependencies...
cabal: internal error: could not construct a valid install plan.
The proposed (invalid) plan contained the following problems:
Package uniplate-1.1 has an invalid configuration, in particular:
  the package has a dependency base >=3 but no package has been selected to sati
sfy it.
  the package has a dependency containers -any but no package has been selected
to satisfy it.
  the package has a dependency mtl -any but no package has been selected to sati
sfy it.


But doing it the old way:

C:\Neil\uniplate>runhaskell Setup configure --hugs
Configuring uniplate-1.1...

C:\Neil\uniplate>runhaskell Setup build
Preprocessing library uniplate-1.1...
Building uniplate-1.1...

C:\Neil\uniplate>runhaskell Setup install
Installing: C:\Program Files\Haskell\hugs\packages\uniplate
Registering uniplate-1.1...


It seems like if cabal install is incapable of doing anything good on
Hugs, it should at least try to see if it works already.

Thanks

Neil
