How to install twisted 10.2.0 with pypy 1.4.1?

I can't install twisted 10.2.0 to my ubuntu box. After download twisted source I issue the command: pypy setup.py install. After that I receive the error:

building 'twisted.runner.portmap' extension

So, how can I fix it? Thanks.

That's a "bug" in twisted build. It might be or might not be a bug - twisted does not consider it's C extensions optional, although they're far from necessary for the most part. Twisted would still work if you just point PYTHONPATH to where it is situated, but without those C extensions.

You may be able to skip building extensions by commenting off the following line in setup.py (73):

       conditionalExtensions = getExtensions(),

This should avoid collecting and trying to build extensions scattered in the directory tree.

As for now Twisted trunk could be compiled OK with PyPy (I used 1.6.1-dev0). However in order to install Twisted you'd need to apply a patch to zipfile.py that I have submitted to stdlib.

zipfile.py 2.7.1+ leaks file descriptors because of CPython-oriented programming style used in zipfile.py

Therefore installation fails under PyPy that uses other GC model than CPython does.
