[Discuss-gnuradio] Undefine symbol

[Joe Barr]

I've just installed gnuradio from subversion on Ubuntu Feisty, per the
instructions at http://gnuradio.org/trac/wiki/UbuntuInstall.  Everything
seems to have gone ok, but when I try to run the benchmark in pthon, I
get:

undefined symbol: _Z20gr_make_io_signatureiii

Any idea on where I might have gone wrong?

Thanks,
Joe Barr
