------------------------------+---------------------------------------------
Currently GHC assumes that the ```python``` command defaults to Python
2.x, but on
some systems (e.g., Arch Linux) it's already Python 3.x. This breaks the
testsuite completely. According to
http://www.python.org/dev/peps/pep-0394/ on
*nix systems one should prefer ```python2``` command. I'm not very
familiar with the
build system of GHC but my quick solution is to:
- make configure.ac check for python2
- make the testsuite also try python2 first
- remove the shebang line from ```calibrate``` (testsuite/timeout) since
make already calls it with the value
of ```PYTHON``` variable
- change the shebang in ```timeout.py``` (in testsuite/timeout) to use
python2, which
should be safe on Unix like systems (and on Windows we don't actually
use timeout.py)
Btw is the ```PythonCmd``` (defined by configure.ac) actually used
somewhere -- I can't
seem to find where...
