Hi, 

I get the following error while making ffmpeg with libilbc enabling:

Even though ffmpeg's configure script does not report any error, I have no idea for this kind of error in make phase.  Please help me!!

My configure option is:
$ ./configure --prefix=/Volumes/ffmpeg_compile" --pkg-config-flags=--static --enable-libilbc

NOTE:
I know libilbc have updated on September 18th.  With this update, libilbc can not be built with cmake.  So I build it with the following procedure:

$ cd libilbc
$ libtoolize
$ aclocal -I m4
$ autoheader
$ automake -a -c
$ autoconf
Note that I build each auto tools with "./configure --prefix=/Volumes/ffmpeg_compile" option.

$ ./configure --prefix=/Volumes/ffmpeg_compile --disable-shared
$ make
$ make install
