         libg2c.so.0 => /usr/lib64/libg2c.so.0 (0x0000002a95743000)
         libm.so.6 => /lib64/tls/libm.so.6 (0x0000002a95864000)
         libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000002a959ea000)
         libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a95af6000)
         /lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000)

Interesting, so it seems like it is NOT linking to /usr/local/lib/ 
libfftw3*, despite scipy.show_config() saying that it is.
