I took a look. From the dumpinfo perspective, there have to be either:
1. two distinct packages (luapuc and luajit) that provides lua, liblua, etc.
2. virtual packages (lua,liblua,etc) that requires either luapuc/libluapuc/... or luajit/libluajit.

Here are sample patches for the second approach:

For both ways there is a problem with BuildHost. It's not possible to split luapuc/luajit to separate directories while the host build path cached in tmp/.packagedeps.
I still looking for a way how to build two different packages (from different sources) from one Makefile.
