GHC.TypeLits not installed properly?

[mstksg]

Hi,

I'm trying to install linear-1.4 on the vm and I ran into a compile error that I mentioned on their issue tracker ekmett/linear#28

I think I've tracked it down to that both ghc and ghcjs don't have properly working installations of GHC.TypeLits, or it's at least not knowing it's there when it is trying to build linear.

Is this a known/common issue; are there any ways i might be able to resolve this?

Maybe a newer version of TypeLits is needed?

Might have been a problem with some GHC 7.7 prerelease, but it looks like it works now, with linear-1.6.

I've updated the vagrant config and the prebuilt, so an update should fix this.
