I'm just running tests because I want Boost to be usable on QNX. 
Boost.Python is not a library I foresee myself using so I'm not inclined to 
spend a lot of time on it. This suspected issue of Python version 
compatibility is probably not limited to QNX, but you may be able to learn 
about it by looking at my test results.

Just go to the develop summary matrix for Python and click on the failures 
in the "NA-QNX650-SP1-x86" column. I'll give you a taste:

test python - args:
  File "../libs/python/test/args.py", line 4
    from __future__ import print_function
SyntaxError: future feature print_function is not defined

test python - bienstman3:
<doctest __main__[1]>:3: Warning: 'as' will become a reserved keyword in 
Python 2.6
File "../libs/python/test/bienstman3.py", line 7, in __main__

test python - builtin_converters:
  File "../libs/python/test/test_builtin_converters.py", line 5, in <module>
    if (sys.version_info.major >= 3):
AttributeError: 'tuple' object has no attribute 'major'

For NA-QNX650-SP1-ARM, Python is present and working on the host running 
Boost.Build, but not on the target. I'm not aware of any way to let 
Boost.Build know this. I've added --without-python but it will take a day or 
two before the tests are re-run.
