Can't compile from source

Hi, I'm trying to compile from source, but there are some errors:
When I execute ./autogen.sh, the following happens

rasca@macbook:~/isight/mainline$ ./autogen.sh

  testing autoconf2.50... not found.

Please add the files
  codeset.m4 gettext.m4 glibc21.m4 iconv.m4 isc-posix.m4 lcmessage.m4
  progtest.m4
from the /aclocal directory to your autoconf macro directory
or directly to your aclocal.m4 file.
You will also need config.guess and config.sub, which you can get from
ftp://ftp.gnu.org/pub/gnu/config/.

I downloaded the lastests source. Any idea why I can't compile? Thanks.
