guess you already removed the config.cache and recompiled.
anyhow it did find everything.

when creating the [pix_film] object the first time it should display the 
used libraries (like "libmpeg3" ).
I guess it does not, meaning that the configuring somehow didn't really 
do what it should
Open the src/Base/config.h file.
Edit it as appropriate (set values to one or define them like
#define HAVE_LIBMPEG3_H 1
#define HAVE_MPEG3
), similar for quicktime

i do know that the configure script + config.h are somehow broken but
of course i need time....
