Sorry, I thought Raspbian was Debian based. In any case installing autoconfig solved a host of problems. Unfortunately not all. Let me know if I need to go to the raspian forum but following black_eagle's instructions the command 'make package-inputstream.ffmpegdirect' ran for a long time looking like it was working. However, eventually it spit out the following:

You have another version of autoconf. It may work, but is not guaranteed to.
If you have problems, you may need to regenerate the build system entirely.
To do so, use the procedure documented by the package, typically 'autoreconf'.
