no, I just call "ghc --make ..."

When I add "-hide-package text-1.0.0.0" to the command line, then 
compilation goes through, but linking fails.

Obviously, having two versions is bad. Maybe I should install the old 
text version explicitly first and reinstall all other packages.

Or I wait until warp can work with text-1.0.0.0, too.
