As has already been mentioned, you system is still trying to use
wxPython 2.5.3. You can see this is so by looking at the path
referenced in the error, quoted above. You need to have properly
installed wxPython >= 2.6, and verified the system finds that instead.

Hello Sir,
Actually i was trying to install
python-wxPython-2.8.9.1-1.el4.pp.src.rpm but somehow it could not be
build.So i had to go with the wx-2.5.3-gtk2-ansi.Even i had tried with
the wx-2.8.3-gtk2-ansi but python 2.4 (abi) is required.Can u just tell
me what should i do??In which directory does the rpm
“python-wxPython-2.8.9.1-1.el4.pp.src.rpm” gets installed.I m having
problem with the usrp_fft.py program only.

I am really very new to the Gnuradio installation.So kindly help me
out.
