Hi and thanks for the help, yes ive run it (and ive renamed the block to 'test' instead of 'howto_2' but i still get something wrong obviously because when running the test script i get this error:

  File "./qa_test.py", line 6, in <module>
    from gnuradio import gr, gr_unittest, test
  File "/Library/Python/2.5/site-packages/gnuradio/test.py", line 21, in <module>
    import _test
ImportError: dlopen(/Library/Python/2.5/site-packages/gnuradio/_test.so, 2): Symbol not found: __ZTV14test_double_ff
  Referenced from: /Library/Python/2.5/site-packages/gnuradio/_test.so
  Expected in: dynamic lookup

it seems like there is something wrong in the swig-generated _test.so file but how to fix that i have no idea?

There are a number of things that could be going wrong with the
process from configurations to building and installation.

First:  Have you re-run the "bootstrap" script?  This reads the
Makefile.am files to create the Makefile.in files.  Then the
"configure" script takes the Makefile.in files and creates the
Makefiles for building.

So try running through the whole process again:
sudo make install
