Prerequisites:

Install autoconf and libtool, so you can generate the configure scripts.
Install SDL2 and GLEW, because this software requires SDL and OpenGL.

To build:

$ autoreconf -if
$ ./configure
$ make
$ make install

Problems:

$ libtoolize
$ automake --add-missing

./configure: line 15095: syntax error near unexpected token `sdl2,'
./configure: line 15095: `  PKG_CHECK_MODULES(sdl2, sdl2 >= 2.0, with_sdl2=yes, with_sdl2=no)'
