This doesn't look like a problem with pyprof2calltree but instead a problem with distribute and/or your environment.

As far as I understand it, distribute is now deprecated for a long time and replaced by setuptools. See the note about that here: https://pypi.python.org/pypi/distribute/0.6.49. The most recent version of distribute simply installs setuptools: https://pypi.python.org/pypi/distribute/0.7.3

Please try updating pip, setuptools and distribute (or remove it) to the latest versions and try again.

yeah, it's my problem, sorry to trouble you, and thanks for your suggestion.
