Two different Pythons, which give different behaviour.

Self-compiled Python 3.3,

$ which python3
/Users/peterjc/bin/python3
$ python3 --version
Python 3.3.0

Apple provided Python 2.7,

$ which python
/usr/bin/python
$ python --version
Python 2.7.5

OK, that's informative - I wasn't sure if you'd tried this under Mac OS X.

Try https://gist.github.com/peterjc/8334631 which extracts the
failing Biopython unit test as a short script. I'm working on
further simplifying it - currently in addition to ReportLab it
requires Biopython (using Biopython 1.63 should be fine).

I've not yet tried this under Linux, but could do so as well...
