About bash.bashrc question

Hi:

I need use some tools, they need modify the /etc/bash.bashrc file (In
cygwin)
Add follow words

PATH=/bin/sox-14.3.0:$PATH
export PATH
PATH=/Julius/bin:/HTK/htk-3.3-windows-binary/htk:$PATH
export PATH

But, If I do this, I can’t run gnuradio example files, like follow
error:

emily@ncku-34be181a97
/usr/src/gnuradio-3.2.2/gnuradio-examples/python/digital
$ ./benchmark_tx.py -f 900M
Traceback (most recent call last):

"/usr/lib/python2.5/site-packages/gnuradio/gr/gnuradio_swig_py_runtime.py
", line 6, in
import _gnuradio_swig_py_runtime
ImportError: No such file or directory

How can I do?
Thanks in advance.
