Dear Shay,

I don't own a mac system, so I can't really test myself, but is seems to
me that this report relates to the same problem:

http://stackoverflow.com/questions/6324912/issue-installing-python-module-on-osx-10-6-and-with-gcc-4-0-and-4-2

Allegedly, it is an incompatibility between the version of Xcode and
Python. On the python release page for 2.7.3 there is a note:

`Also, on Mac OS X 10.6, if you need to build C extension modules with
the 32-bit-only Python installed, you will need Apple Xcode 3, not 4.
The 64-bit/32-bit Python can use either Xcode 3 or Xcode 4.'

Therefore, I'd suggest you install the 64-bit version of Python if you
haven't already. If you have, the problem might be somewhere else.
Please do let me know in that case.

Also note that the version of python ccplot is compatible with is
restricted by pynio. Unless you are willing the compile the library from
source (rather complicated), the binaries are available only for python
up to 2.7.1 on the EOS, or 2.6.5 on ccplot.org, even though the version
for 2.7.1 might happen to work with the latest 2.7.3.

Good luck!

Regards,

Peter
