thats weird, what are the permissions on top_block.py?

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

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

Hope that helps,
