Guenter,

It looks like you have build Python yourself (I'm not sure why else it
would be installed into /usr/local). With Ubuntu, just 'sudo apt-get
install python' and use the default installation.

The next best thing, if build-gnuradio still isn't working for you,
use the install instructions for Ubuntu found here:
http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide

Hope this helps.

Tom
