New description:

 Port ninja fails at the build phase, in file configure.py at line 435:

 {{{
 proc = subprocess.Popen(['re2c', '-V'], stdout=subprocess.PIPE)
 }}}

 with

 {{{
 raise ValueError, "insecure string pickle"
 }}}

 using system python (2.7.10) on OSX 10.11


 the offending line also produces the same error using macports python 2.7,
 however it behaves as expected using macports python 3.5. I can get the
 port to build using a custom portfile which uses macports python 3.5
