Can't compile SDL_net on Ubuntu 16.04 64bit

First I compile SDL2:

Code:

hg clone https://hg.libsdl.org/SDL SDL
cd SDL
mkdir build
cd build
…/configure --prefix=/home//libs
make
make install

After SDL is successfully installed. I try to build SDL_net.

Code:

hg clone http://hg.libsdl.org/SDL_net SDL2_net
cd SDL2_net
mkdir build
cd build
…/configure --prefix=/home//libs
make
make install

After make I got error

Code:

CDPATH="${ZSH_VERSION+.}:" && cd … && /bin/bash /home/karlis/test/SDL2_net/missing aclocal-1.13
/home/karlis/test/SDL2_net/missing: line 81: aclocal-1.13: command not found

You should only need it if you modified ‘acinclude.m4’ or
configure.ac’ or m4 files included by ‘configure.ac’.
The ‘aclocal’ program is part of the GNU Automake package:

It also requires GNU Autoconf, GNU m4 and Perl in order to run:

I have installed aclocal-1.15. What to do
