"not running in a graphics-capable console" would imply that neither X nor the framebuffer (I'm kinda leaning towards the framebuffer) is running, and/or that svgalib requires some form of 3D hardware acceleration support which is not installed. I don't know which is the case (I don't know your setup-- i.e., how you're running this program-- or what requirements svgalib has), but presumably your interest in this subject (or the tutorial you're following) should give some kind of a clue as to which area of your graphics subsystem needs to be looked at. As to the mouse thing, well, a Google search for svgalib_helper links to this page, "SM 5 BSZ - Installing svgalib-1.9.19 under different distributions" at http://www.sm5bsz.com/linuxdsp/install/distrib2.htm . Now, naturally, Gentoo is not included, but it does say this for FC3: "To get the mouse going, add a line mdev /dev/input/mice in the /etc/vga/libvga.config file." So I would check to see if there is a libvga.config file on the system, and see if that line is present, and add it if not-- it just might work, although it's also possible that this is related to your original issue with the lack of a graphics-related console insofar as the 'original' basic graphics setup would normally include the mouse, so if the graphics were fixed, the mouse issue might be as well.
