Comment:
Fortunately this has just been fixed. #2445
In future you would get an error message like:
{{{
Could not find module `System.Process':
There are files missing in the process-1.0.1.1 package.
Try running 'ghc-pkg check'.
}}}
And if you ran `ghc-pkg check` it would report something like:
[Note these are just examples and do not match up to the same problem]
{{{
$ ghc-pkg check
There are problems in package syb-0.1.0.0:
dependency foo-4.0.0.0 doesn't exist
There are problems in package process-1.0.1.1:
file System/Process.hi is missing
The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
syb-0.1.0.0
process-1.0.1.1
base-3.0.3.0
Cabal-1.7.0
haskell98-1.0.1.0
haddock-2.4.2
ghc-6.11
}}}
Of course in your case, where you deleted all the package files without
unregistering any of them, then the list of errors reported by `ghc-pkg
check` would be a good deal longer.
