 While upgrading octave from 3.0.x to 3.2.2 I got two errors, one related
 to gperf (that I actually did not install) and one about missing TeX.

 Notice that I was upgrading the existing octave port so 3.0.x was built
 without both gperf and a tex binary.

 If octave needs those in order to be built then the portfile should
 definitely list them as deps.

 I'm attaching significative excerpts from the output.
