2636	Error message for missing import substantially worse in 6.9/6.11	NeilMitchell	igloo	"Creating a file Test.hs:

{{{
import Foo
main = print ""hello""
}}}

where Foo does not exist, used to give a really nice error (with 6.8.3) but with 6.9 and 6.11 gives a horrible error message:

{{{
$ runghc Test
*** Exception: Could not find module `Foo':
  Use -v to see a list of the files searched for.
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.11.20080929
}}}

Compared to version 6.8.3:

{{{
$ runghc Test.hs

Test.hs:2:7:
    Could not find module `Foo':
      Use -v to see a list of the files searched for.
}}}

A much nicer error, importantly saying where the import was - in my case the import was in an imported module, so I didn't even know which file was causing the error."	merge	closed	high	6.10.1	Compiler	6.9	fixed			Unknown/Multiple	Unknown/Multiple		Unknown
