Lovely, thanks!

Can I change 

- push @dirs, $Config{sitearchexp}, $Config{archlibexp};
+ unshift @dirs, $Config{sitearchexp}, $Config{archlibexp};

[download]
because $sub (in ExtUtils::Installed->new)loops through the @dir array and sets $self->{module}{packlist} so if we push them on then if a module is installed in the dir you specified and in say /usr/local, we will always get back the packlist for /usr/local - which isn't very helpful if you want to uninstall something in a local directory. If you want the /usr/local version, just don't give a local dir in the call to new.

If that change is OK, then I wrote a quick thing for easy command line uninstall. Spot any glaring errors?
