Dear haskell rascals, In an attempt to create a relocatable repository of development tools, I created this simple script to configure/build/install packages from hackageDB. This script is meant to be used in an 'msys' environment on a windows machine.

To quote the Cabal User's Guide (sec 4.1.2.3)

...

A library cannot (currently) be prefix-independent, because it will be linked into an executable whose file system location bears no relation to the library package

So far, this attempt has been successful for me. Improvements, criticism, and other solutions are welcome. Thanks.
