Multi-version installations are not well supported by setup or cygwin
yet, but the alternatives anyway only address the question of how to set
the default version for the user.  For building packages you'd need to
specify which version to use each time you build something, so any
occurences of plain "lua" (from PATH) would need to be replaced with the
expansion of some variable that would be set appropriately when entering
pkg_info.

The packages should be named lua53-luarocks and lua54-luarocks (no dot
in the version number), like OpenSUSE (they seem to be the only
distribution with a multi-version lua and that particular naming scheme
you've chosen).

A different question is if you really want to package this particular
feature.  Just like all the other "package managers" that come with a
specific language or interpreter I'd expect this one to need (maybe
extensive) modifications to work correctly on Cygwin, especially if it
ends up building dynamic objects.  That's one reason I discourage the
use of CPAN on Cygwin, since folks tend to shoot themself into the foot
more often than not by using it.
