Summary: file location problems in ghci

Initial Comment:
This bug isn't that important, but it is a little
odd.   If I try to run GHCi in the directory where  the
prelude .hi files are, it can't find the interface
files.   I don't know of any other directories where
this phenomenom occurs, although I did try a number of
the other directories off imports.

The bug is caused by the fact that the standard import path 
(i.e. "." by default) overlaps with the import path for 
package std.

We've fixed it so that home package interfaces are ignored 
when using ghci or ghc --make, with the result that cd'ing 
into ghc/lib/std and starting ghci will just work.

Ahh yes... I have the same problem in
/usr/local/src/ghc-5.00.2/ghc/lib/std
