Swig Error in Python from Trunk Build

I am running Feisty Fawn Ubuntu. I downloaded, built, and installed the
GNU Radio via the trunk following the build directions for Feisty on
http://gnuradio.org/trac/wiki/UbuntuInstall”. As directed, I used the
Ubuntu version of swig since I’m using Feisty. Everything seemed to go
ok. My USRP is recognized via USB. I’m also able to run
“test_usrp_standard_tx” and “test_usrp_standard_rx” from
“usrp/host/apps”. However, when I attempt to run “benchmark_usb.py”
from “gnuradio-examples/python/usrp” I get the following errors:

[email protected]:~/gnuradio/gnuradio-examples/python/usrp$
./benchmark_usb.py
Traceback (most recent call last):
File “./benchmark_usb.py”, line 30, in
from gnuradio import gr
File “/usr/local/lib/python2.5/site-packages/gnuradio/gr/init.py”,
line 27, in

line 6, in
import _gnuradio_swig_py_runtime
ImportError: libgnuradio-core.so.0: cannot open shared object file: No
such file or directory

Am I missing something during the build? Any help would be greatly
appreciated. Thank you.

Double check that you updated /etc/ld.so.conf and run ldconfig?
