I wonder *why* packages need sh though? Isn't cabal supposed to allow you to 
do that kind of scripting in Haskell rather than calling into 
platform-dependent shell scripts? Are there any specific reasons why people 
feel the need to use sh?
If the package is unix-only for other reasons (e.g. bindings to X or 
whatever) then it's obviously not a problem, but it appears to me that 
there's lots of packages that should be portable in principle that won't 
build on windows because it needs to run sh...
