OK, you need to edit the configure.ac file and replace this section:

        AC_CHECK_LIB(xvidcore,xvid_encore,[
                AC_MSG_CHECKING([for XviD version 1.0.0])
                AC_RUN_IFELSE(
                        AC_LANG_PROGRAM([[#include <xvid.h>]],[[
                           exit( XVID_VERSION_MAJOR(XVID_VERSION) !=3D 1 );
                           ]]),
                [
                        AC_MSG_RESULT(yes)
                        LIBS=3D"-lxvidcore $LIBS"
                        build_encoder_mpeg4=3Dtrue
                ],[
                        AC_MSG_RESULT(no)
                        if test x$enable_encoder_mpeg4 !=3D xauto; then
                                AC_MSG_ERROR([XviD is too old])
                        fi
                ])
        ],[
                if test x$enable_encoder_mpeg4 !=3D xauto; then
                        AC_MSG_ERROR([Unable to find libxvidcore.so])
                fi
        ])

with this:

        AC_CHECK_LIB(xvidcore,xvid_encore,[
                        LIBS=3D"-lxvidcore $LIBS"
                        build_encoder_mpeg4=3Dtrue
        ],[
                if test x$enable_encoder_mpeg4 !=3D xauto; then
                        AC_MSG_ERROR([Unable to find libxvidcore.so])
                fi
        ])

and run autoconf to rebuild the configure script.  Then you will be able=20
to run configure and it will detect XviD.  -Nathan
