I imagine luarocks may work similar to Perl's CPAN on Cygwin: some
Perl modules can be installed via Cygwin's setup.exe (e.g. perl-Tk,
perl-Data-Dump), the rest can be installed with the CPAN client.

IANALU (I am not a Lua user), but it seems to me that these Lua
modules should be outside the scope of Mudlet's cygport. Mudlet should
simply require these modules to be present for its Lua subsystem. The
user can be directed to install the required modules by whichever
means available (rex_pcre and luasql.sqlite may be too complicated to
be installed by luarocks; they may need to be made into Cygwin
packages like lua-file-system).

Mudlet should not mess with the user's Lua installation.
