Comment 1 Tom Henderson 2012-04-23 17:24:00 UTC

could not reproduce today on three different machines:

- my Linux machine
- ns-buildmaster
- darwin (also an OS X machine)

Comment 2 John Abraham 2012-04-23 17:26:12 UTC

I believe this is probably seen in machines which don't have bzr.  i have to check

Could not reproduce this on a new Ubuntu 12.04 32-bit machine that had mercurial and python-dev installed, but did not have bzr installed.  The pybindgen report is:

    #
    # Get PyBindGen
    #
    
Required pybindgen version:  0.15.0.809
Trying to fetch pybindgen; this will fail if no network connection is available.  Hit Ctrl-C to skip.

 *** Did not fetch pybindgen; python bindings will not be available.


Repeated calls to ./download.py produce the same (expected) output.


Suggest to close as INVALID?

Comment 4 John Abraham 2012-08-24 17:53:36 UTC

actually I reported this on the mac. I tried something similar now

Doing keyboard interrupt prevents ./download.py from working again. a similar concept maybe applicable for mac without bzr?
