Here is the flow graph console output:

address@hidden:~/gnuradio/prefix/perform$ gnuradio-companion

Here is an excerpt from the PyBOMBS output:

PyBOMBS.install_manager - INFO - Installing package: apache-thrift
Install tree:

\- gnuradio
   |
   +- uhd
   |
   \- apache-thrift

Here is the output from gnuradio-config-info --enabled-components:

Thanks for your help,
