There should be no BDEPEND in the eclass any more, it's a leftover from
an earlier iteration which retrieved module directories in less
conditional fashion.

Will add "or package.use" here.

Should be "proper Lua executables" - for dev-lang/lua we have got both
'lua' and 'luac', and for dev-lang/luajit we'll probably have 'luajit'
(have yet to see if invoking 'luajit' as 'lua' works).

Just say "minus" here, as it stands it is a bit confusing (at least to
me) because my first reaction is to read the - as a dash, not as an
arithmetic minus.
