Installing Downpour bittorrent client

Question

I'm trying to install Downpour (http://jongsma.org/downpour/#install) on my new Macbook pro. I am running the command "pip install Downpour", but I get the error:

Downloading/unpacking Twisted-Core>=8.2.0 (from Downpour)
  Could not find any downloads that satisfy the requirement Twisted-Core>=8.2.0 (from Downpour)
No distributions at all found for Twisted-Core>=8.2.0 (from Downpour)

So then I try installing Twisted by itself running the command "pip install Twisted" but I get the following error:

Requirement already satisfied (use --upgrade to upgrade): setuptools in /sw/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg (from zope.interface->Twisted)

Answer 1

The python you are using is in /sw so I would assume it is from Fink if so you should also install Twisted from Fink whcih will be one or more of the packages listed here

The problem you are seeing is that python was built as a 32 bit application and setuptools is trying to build as a 64 bit. This suggests that they were not installed from the same place/
