[AL] mapped files error

[ed j. <re...@ya...>]

Hello all, 
I have recently bought the Game Programming All In One
book and attempted to install on a Fedora Core 3 Linux
box and I am partially successful up until the end of
the make install, then I get an error as such:

gcc -DHAVE_CONFIG_H -Iinclude -Iinclude/allegro
-I./include -I./include/allegro -I. 
-I/usr/X11R6/include  -I/usr/include/kde/artsc
-pthread -I/usr/include/glib-2.0
-I/usr/lib/glib-2.0/include   -DALLEGRO_LIB_BUILD
-mcpu=pentium -O2 -funroll-loops -ffast-math
-fomit-frame-pointer -Wall -Wno-unused -fPIC
-DALLEGRO_SHARED -c ./src/linux/lmemory.c -o
obj/unix/shared/alleg/lmemory.o
./src/linux/lmemory.c:27:2: #error "Sorry, mapped
files are required for Linux console Allegro to work!"
make: *** [obj/unix/shared/alleg/lmemory.o] Error 1

any help would be appreciated, 
Thanks, Ed.
