import prefers module in package over local module

[Michael Marte]

Hello *,

I am migrating a project from ghc 6.2 to ghc 6.4. This project has a 
module called Pretty and that's where my problems start. When importing 
Pretty, ghc does not consider my local definition but the Pretty module 
from the standard library (which is an alias for 
Text.PrettyPrint.HughesPJ). Is this behaviour intended or is it a bug? 
Can I change it? If it is intended, can somebody explain the rationale 
to me?

BTW, I am using -hidir and -odir and the latest Debian package 
containing ghc 6.4.1.

Thank you,
Michael
