---------------------------------+------------------------------------------
On an Intel {{{MacBook}}} with Mac OS X 10.6.5 (Snow Leopard), with GHC
6.12.3 from a standard Haskell Platform installation,
System.Directory.doesDIrectoryExist always returns False for any path.
This issue was first reported here: http://www.haskell.org/pipermail
/haskell-cafe/2010-November/086603.html
At that time, several other users on the same platform responded that
they were not experiencing the problem. I also tested at that time, and
I did not experience the problem.
Now it has started happening here. During the past day I upgraded
some basic packages from Hackage, so I suspect that is related.
I have tried it with directory-1.0.1.1
and filepath-1.1.0.4 as originally supplied with the HP install, and also
with directory-1.1.0.0 and filepath-1.2.0.0 from hackage, all with
the same problem occurring.
One of the packages I upgraded was unix, from 2.4.0.2 to
2.4.1.0. I tried hiding the newer version, but when I run
doesDirectoryExist and GHCi loads the directory package,
it ignores my hiding and loads the newer unix package.
If I both hide the newer unix package and manually specify
the older one, GHCi complains about duplicate symbol
definitions and departs.
All of that is especially strange, since unix is not even
a dependency of directory.
