[Discuss-gnuradio] how_to_square_error

[Vincenzo Pellegrini]

In my previous installation, still on fedora core 6 I did not experience this but right now,
when make checking into the src/python directory after having compiled the gr-howto-write-a-block stuff

I get this error:

ERROR: test_002_square2_ff (__main__.qa_howto)
