minetest on debian wheezy

[yanlolot]

Hello

I've installed minetest on debian wheezy, but when I launch it, I've a window with client and server.
No single player anywhere.
Here's the launch with a console:
$ minetest
signal_handler_init()
Using system-wide paths (NOT RUN_IN_PLACE)
path_data = /usr/games/../share/minetest
path_userdata = /home/yanlolot/.minetest
Debug streams initialized, disable_stderr=0
15:56:40: ACTION[main]: minetest with SER_FMT_VER_HIGHEST=20, VER=0.3.1 RUN_IN_PLACE=0 USE_GETTEXT=1 INSTALL_PREFIX=/usr BUILD_TYPE=Release
INFO: Initial run of init_mapnode with g_texturesource=NULL. If this segfaults, there is a bug with something not checking for the NULL value.

OpenGL driver version is 1.2 or better.

Could not load font because the file does not exist:

So I can't play.
