transcode: 1.0.5_3 => 1.0.6_1 fails at configure(gnome-config)

[Henry Hu]

My configure log says:
...
checking ffmpeg/avcodec.h presence... yes
checking for ffmpeg/avcodec.h... yes
checking libavcodec/avcodec.h usability... no
checking libavcodec/avcodec.h presence... no
checking for libavcodec/avcodec.h... no
checking for pkgconfig support for libavcodec... no
checking for avcodec_thread_init in -lavcodec... yes
...

And the configure process finished normally.
My version of ffmpeg is 2007.10.04, rather old.
So I think the line
checking for avcodec_thread_init in -lavcodec... yes
is critical.
And where does your libavcodec/avcodec.h come from ?
