 When trying to install Cairo with the new Haskell Platform (2011.2.0.0). I
 get the error:

 {{{
 > cabal install cairo --ghc-option=-DCABAL_VERSION_MINOR=10
 ...
 Registering cairo-0.12.0...
 setup.exe: internal error: unexpected package db stack: [UserPackageDB]
 ...
 }}}

 The CABAL_VERSION_MINOR flag is suggested if you try without it but
 doesn't make a difference in the outcome.

 I'm on Windows 7 64-bit.

 {{{
 > cabal --version
 cabal-install version 0.10.2
 using version 1.10.1.0 of the Cabal library
 > ghc --version
 The Glorious Glasgow Haskell Compilation System, version 7.0.2
 }}}

 Attached is the -v2 log.
