Hi,
“Python” is just mentioned there as one of the paths in your LD_LIBRARY_PATH; there’s nothing further to it, and it could as well have been named peanut_butter.
The problem is a missing libFFTW.so, which probably just means that fftw3 was not enabled. You can check that with root-config --has-fftw3. If the answer of that is ‘no’, then that’s the issue. (If it isn’t enabled, then that is most likely b/c libfftw3.so is not installed (or was not during build time).)
HTH,
Wim
