webcam stuff (Skippy especially)

[Net Llama!]

Keith,
I've just about caught up to you here.  I'm trying to build 
linuxvideostudio, and the compile is bombing out here:
gcc -DHAVE_CONFIG_H -I. -I. -I..     -O2 -funroll-loops -ffast-math 
-malign-double -mcpu=pentiumpro -march=pentiumpro -f
omit-frame-pointer -fno-exceptions -c -o libyuv4mpeg_a-y4m12.o `test -f 
y4m12.c || echo './'`y4m12.c
In file included from y4m12.c:8:
y4m12.h:5: yuv4mpeg.h: No such file or directory
make[2]: *** [libyuv4mpeg_a-y4m12.o] Error 1

The odd thing is, the file that it can't find appears to only be a part 
of mjpegtools-1.6, and not 1.4 (even though both are supposed to work).
