Thanks! Got it. Seems that the default autogen doesn't make the libraries, or install the headers. I needed to do this: ./autogen.sh --enable-libraries ( Then make and sudo make install. Then it puts the stuff where pip finds it. Your test below, now works for me. Very nice code to have! Thanks for the help as well. --Adam On 3/8/13 1:44 PM, "James Goppert" <jam...@gm...> wrote: >It looks like whatever branch you are using isn't getting the headers >installed properly.
