ImportError: cannot import name uhd

Hi,

I’ve installed gnuradio following this guide:
http://www.mail-archive.com/[email protected]

When I install my gnuradio/uhd stuff into a non-standard prefix, I setup
the paths in .bashrc like so:

export PKG_CONFIG_PATH=usr/lib/pkgconfig:${PKG_CONFIG_PATH}
export PATH=usr/bin:$PATH
export PYTHONPATH=usr/lib64/python2.6/site-packages:$PYTHONPATH
export GRC_BLOCKS_PATH=home/ccss/gnuradio-uhd/gnuradio/grc/blocks
export LD_LIBRARY_PATH=usr/lib

But when I try to run python /gr-uhd/apps/uhd_rx_cfile.py I get this
error:
Traceback (most recent call last):
File “uhd_rx_cfile.py”, line 30, in
from gnuradio import uhd
ImportError: cannot import name uhd

Has anyone else had this problem or know a fix for it?
