Yes, we lack optional dependencies... it's not clear how to proceed
with those if we had that feature, since the luarocks command is not
interactive. Perhaps just suggesting the user about them at the end of
installation?

Well, that is one possibility, with a build.type="none".

That is always another possibility... if the user will have to figure
out they have to run 'luarocks install pop3-auth-cmd5' to get that
support, you could just tell them to run 'luarocks install lua-crypto'
instead.
