a DDG search for PyInt_FromLong gave me this link : http://docs.python.org/2/c-api/int.html
another search for 'PyInt_FromLong python3' gave this : http://python3porting.com/cextensions.html
In short libactp looks like a python2 library, try building it against python2 .
]]>I'm downloading source from www.github.com/Heeks/libactp and running the below commands...
$ cd PythonLib
$ make
And that is where I get the error. Not sure if I have all the information needed but this is the first time I have not been able to build something on this machine!
