 Cal brought this up in [http://trac.macports.org/ticket/38198#comment:6
 #38198comment:6] and I had been thinking of it myself independently
 before, so I decided to open a separate ticket for it. Anyway, it would be
 useful to specify dependencies that are only used when running tests, such
 as `expect`, for example. (This is kind of similar to my request in #38112
 btw, just for a different phase)
