Assistant/Alert.hs:21:8:
    Could not find module `Text.Blaze'
    It is a member of the hidden package `blaze-markup-0.5.1.1'.
    Perhaps you need to add `blaze-markup' to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.

What is the expected output? What do you see instead?

I expect the latest git HEAD to build without an error message or provide me with a package I need to install. Instead the error above is shown. In fact the package requested is installed:

<pre>
dominik@Atlantis:/var/tmp/git-annex$ cabal install blaze-markup

All the requested packages are already installed:
blaze-markup-0.5.1.1
Use --reinstall if you want to reinstall anyway.
</pre>

What version of git-annex are you using? On what operating system?

git HEAD, Ubuntu 12.10

Please provide any additional information below.

<pre>
$ cabal --version
cabal-install version 0.14.0
using version 1.14.0 of the Cabal library 

$ ghc --version
