[grobbelaar@…]

I tried to 'sudo port install ninja', but it failed with

The log contains:

The problem seems to be that even though I have Python 2.7 via MacPorts (which python -V says 2.7.11), bootstrap.py begins with #!/usr/bin/python, and that is 2.3.5 on this PPC Mac Mini with OS X 10.4.11 :(

#!/usr/bin/env python selects the "active" Python.
