mtl is the Monad Transformer Library.  It's a part of the standard libraries

set of libraries the GHC ships with; it may be that mtl is on that list.  I 
haven't really been following, so I'm not sure.

  
Maybe there's something broken in this GHC 
snapshot. I've already noticed Template Haskell seems to be broken in it.
    

Possible.  I also notice that QuickCheck isn't in your list of installed 
packages.  You'll need that to compile edison-core.

  
OK, now I've uninstalled GHC 6.5.x, and installed 6.4.2, and now I can compile Edison without any problem. I think that 6.5.x snapshot was missing some libraries. Three cheers for stable releases.
