That in particular talks about user-settable variables, package-settable variables, and variables defined by the file. You should only set user-settable variables in mk.conf. > Initially, no.

That's not a user-settable variable, so that's basically a wrong thing to do. > That got me past the first failure, with py-libxml2, but introduced a > problem with the next, py-libxslt, which still wants python2.7.
