Looks like cygport, calm, and setup disagree about install dependencies; from
setup.ini:
bzr
requires: python
depends2: python
python
requires: python2
depends2:
python2
requires: python27
depends2:
so although python requires python2, and python2 requires python27, the (newer)
depends2 entries are not the same and are empty, so setup ignores requires and
does not install the dependency.
In these cases, either depends2 should be the same as requires, or depends2
should be omitted, and setup should install requires.
