Hi Daniel, I experienced this problem yesterday and reported the issue here: http://hackage.haskell.org/trac/gtk2hs/ticket/1203 With some small changes to the Gtk2hsSetup.hs it registers successfully. Hope this helps, Ryan http://hackage.haskell.org/trac/gtk2hs/ticket/1203 On Sat, Mar 12, 2011 at 9:18 AM, Daniel Díaz wrote:

Hi, cafe,

When I have updated my Haskell Platform version to 2011.2.0.0, and I try to install cairo or glib, during the registering I read the following:

Registering glib-0.12.0... Installing library in C:\Documents and Settings\User\Datos de programa\cabal\glib-0.12.0\ghc-7.0.2 Registering glib-0.12.0... setup.exe: internal error: unexpected package db stack: [UserPackageDB]

And then, the instalation fails.

Searching in Google, I have found some links related:

* http://www.mail-archive.com/haskell-cafe@haskell.org/msg81071.html

* http://hackage.haskell.org/trac/hackage/ticket/731

But I never had this problem before.

Thanks for any help, Daniel Díaz
