Comment (by ryandesign):

 Because this port fetches from the git repository, which does not contain
 a configure script, the port has to generate it from configure.ac. If what
 got generated doesn't work, manually editing the generated file won't be
 the right solution; instead, editing the configure.ac file from which it
 was generated is what's needed. Likely, the configure.ac script contains
 some error that old versions of autoconf were not sensitive to but which
 the version of autoconf which we use now fails on. This is likely a
 problem that has already been solved in the upstream repository, so
 updating the port is the first thing I would suggest trying.
