There is no easy way to remove modules installed via CPAN.  You can
Google how to do it, but it's mostly manual.  You also need to
consider how to handle dependencies that were pulled in.

To avoid this in the future, only install packages using the package
manager (i.e. cygwin setup), and for anything that's not in there, use
the perl local::lib module to setup a dedicated location for any
additional packages you need.
