Deprecation warnings seem to be working fine:

$ ghc -c Foo.hs -package text

Foo.hs:2:0:
    Warning: Module `Pretty' is deprecated:
                 This module has moved to Text.PrettyPrint.HughesPJ

Also, the documentation for the text package clearly states in several
places that the modules it contains are deprecated.

Ok, if you encounter the problem again in the future, please save the
details and send them to us.
