liballegro4.2 binary package in Ubuntu Precise armhf

 Allegro is a cross-platform library intended for use in computer games
 and other types of multimedia programming. It is used by many DOS games
 and can be used to port them easily to Linux. Allegro supports many
 kinds of input and output interfaces, e.g. X11 (Xlib or DGA),
 framebuffer, SVGAlib.
 .
 NOTE: you should install XFree86 to use the display output plugins.
 Alternatively, you can use the framebuffer output, or install the
 liballegro-plugin-svgalib on i386.
