INSTALL alternative fails with ImportError

[LarryE]

With OS ubuntu16.04, downloaded code with:

  bzr branch lp:pybridge

then followed the INSTALL instructions:

Alternatively, you can run PyBridge from the extracted tarball archive. Change
to the PyBridge 'bin/' directory, then type './pybridge' to run the graphical
client, or './pybridge-server' to run the standalone server.

However, this resulted in the ImportError:

evansl@lje-OptiPlex-9020:~/dwnlds/pybridge/launchpad/pybridge/bin$ ./pybridge
Traceback (most recent call last):
  File "./pybridge", line 60, in <module>
    main()
  File "./pybridge", line 51, in main
    from pybridge.common.dependency import verify_pybridge
ImportError: No module named common.dependency
evansl@lje-OptiPlex-9020:~/dwnlds/pybridge/launchpad/pybridge/bin$

Please ignore.

The problem was caused by having a previously installed version from sourceforge.
When that was rm'ed, ./pybridge didn't show the ImportError.

Sorry for noise.
