I guess one can add a line
library_dirs = /usr/lib64
to the corresponding lines in system_info.py. Does this fix the problem
of detecting the fftw libraries ?
[fftw]
fftw_libs = rfftw, fftw
fftw_opt_libs = rfftw_threaded, fftw_threaded
# if the above aren't found, look for {s,d}fftw_libs and {s,d}fftw_opt_libs
