Comment (by RJVB):

 To be precise, `${configure.dir}` and `${build.dir}`, and no, they are not
 created automatically.

 The cmake PG creates the former (and thus normally the latter too) as the
 first thing in its pre-configure block. I missed that yesterday :-/

 So yes, a feature (or pull!) request to ascertain that ${configure.dir}
 exists before starting the port (pre)configure code would be welcome IMHO,
 idem for ${build.dir} and the build code.

 After all, this happens with ${destroot.dir}, no?

 Of course that still leaves us with the current situation for a certain
 time, until the change makes it to a released "base" version and onto all
 user systems (I'd never support a change that forces users to upgrade
 MacPorts itself before being able to apply what could be a minor port
 upgrade).
