Build failed, can't download autoconf and other tools

On MacOS, when i try to build 3.6.0b12 or 3.6.1.b1, the script always fail downloading autoconf and other tools. The script try:

curl -f -L -- "http://downloads.videolan.org/pub/contrib/autoconf/autoconf-2.71.tar.gz"...

but on this repo there is only autoconf-2.69

Same with http://downloads.videolan.org/pub/contrib/automake/automake-1.16.5.tar.gz

Latest version on repo is automake-1.16.1.

A part of the log is:

autoconf not found
automake not found
m4 too old
libtool not found
pkg-config not found
cmake not found
yasm not found
ragel not found
protoc not found
ant not found
xz not found
bison too old
nasm not found
help2man not found
meson not found
ninja not found
To-be-built packages:  autoconf automake m4 libtool pkg-config cmake yasm ragel protoc ant xz bison nasm meson ninja

The buildMobileVLCKit.sh just stop after checking these tools and don't build.

Step to reproduce:

git clone  --depth 1 --branch 3.6.1b1 http://code.videolan.org/videolan/VLCKit.git VLCKit-3.6.1b1
cd VLCKit-3.6.0b12   
./buildMobileVLCKit.sh -f -b
