[Pythonmac-SIG] py2app testing modulegraph

[engelbert gruber]

hi

i am trying to setup a modulegraph test that triggers missing import
for ifilter, imap

some hurdles

* i am not at a mac currently.

  a good thing, this results in cross platform tests

* altgraph must be installed because pkg_resource require does not
find it otherwise

  this is not so good, as i prefer not to install things but just
copy/symlink especially
  while developing

* modulegraph.util uses ::

    if sys.version_info[0] != 2:
        import re
        cookie_re = re.compile(b"coding[:=]\s*([-\w.]+)")

  it is correct, that this wont be executed for python versions 2.*,
  but it will be compiled and the syntax ``b"something"`` works
  only from 2.6 up

cheers
