FWIW, 1.3.25 works fine with the CVS code.

I think something is slightly screwed in your installation.
Not exactly sure what, but I suspect some environment variable.

Try this and send the output

$ env | grep PYTHON

$ python
>>> import sys
>>> sys.path
>>> from gnuradio import gr
>>> <ctrl-d>

Where is _gnuradio_swig_python.so installed?  It should be in
PREFIX/lib/python2.X/site-packages/gnuradio/gr.  Where X is replaced by your 
python version.

You should have a _gnuradio_swig_python.so file there.  E.g.,
-rwxr-xr-x  1 eb wheel 7065004 Oct 23 21:45 _gnuradio_swig_python.so

Is that path (up to the site-packages part) in the output of sys.path?

Then ldd should give something like this:

address@hidden eb]$ ldd
