* numpy 
    * ctypes 
    * FFTW3
    * OpenMP
As both setuptools and distutils do not have any clear method of support for distributing C libraries for ctypes, the onus is on the user to ditribute the c libraries once built
- 
Clone or download the git repositry from https://github.com/ewanbarr/sigpyproc 
- 
Unzip and untar if needed and move to source directory 
- 
Make sure FFTW3 has been compiled with the --enable-floatand--enable-sharedoptions
- 
run sudo python setup.py install
- 
a lib/c and bin/ directories will be created in the source directory 
- 
Distribute the contents of these directories if required 
- 
If you are developing, then append the lib/c directory to the LD_LIBRARY_PATH environment variable
