   ls /usr/local/lib/pkgconfig

should list fftw3f.pc among the known packages.

   PKG_CONFIG_PATH=/usr/local/lib/pkgconfig pkg-config --list-all

should also list fftw3f.pc among the known packages.

   echo $PKG_CONFIG_PATH

should show that PKG_CONFIG_PATH is not defined.  If it is defined as 
anything other than /usr/local/lib/pkgconfig you have a problem; try 
resetting it with

   PKG_CONFIG_PATH=
