Why is it still trying to find ffmpeg version after its found the header file already? which is from the ffmpeg install in first place?
oh BTW this is a slackware release.

OKm we dont seem to be able to close our own tickets on SF.
Please close Justin, the fault lies with slackwares ffmpeg which is built against X
X is not installed, nor should it be on headless servers.
