Comment (by ryandesign@…):

 The pdftk port cannot use a gcc other than 4.5 or 4.7 until those versions
 of gcc can compile java code correctly. (pdftk is written in java.) See
 #22066 and #40058.

 The compilers portgroup seems to be geared towards ports needing to use
 fortran, not those needing to use java. (I did not find any occurrences of
 "java" or "gcj" in the compilers portgroup.)
