[pypy-dev] Cannot use MacPorts PyPy to Translate pypy-c

[Jean-François Caron]

Hi, I am following the instructions here:
http://doc.pypy.org/en/latest/cppyy.html#installation and here:
http://root.cern.ch/phpBB3/viewtopic.php?f=14&t=17018

In the first link, it says I can use a "built-in pypy" to do the translation to make it go faster.  I have pypy 2.1.0 from MacPorts, but it fails with the following message:
<<<

I am now doing the slow translation with CPython (also from MacPorts) with no problems so far.  Is this just a version mismatch between the MacPorts pypy and that expected by the pypy on mercurial?
