The port auto-multiple-choice also use the -latex variant and this work was done to permit evolutions in it. I have no knowledge about the latex world and the different packages/versions… available so I used the more generic latex term.
I'll reverse the semantic logic and add a +mactex variant. I will first see how it is done in other ports.

I don't know why but files installed in the MacTeX hierarchy are not deleted when I uninstall dbatex and the next installation fails because files are allready here.
