[FFmpeg-user] undefined reference to 'ff_find_pix_fmt'

[bryandonnovan at gmail.com]

building 0.6.9-rc0 for win32 with a configuration for writing FLV files...

When libavformat links, it has an unresolved external 'ff_find_pix_fmt'

ff_find_pix_fmt is defined in avcodec/raw.h and avcodec/rawdec.c however it
does not appear in avcodec/avcodec-52.def

So, my main question is -- what change must I make so that it DOES appear in
the DEF file?

My second question is the error "./configure: line 761: pkg-config: command
not found" -- is this a problem?  And if so, what can I do about it?

Thanks

Ouput from configure and link stages below:
