Building on Fedora 8

I'm trying to get a version working on my Fedora 8 AMD-64 machine.   So 
far when I try to build, it fails at the point of building the main.   
I've gotten by many things before this but here I don't see what to do 
to point it to prj.ads.  I can find the file in the gnat subdirectory 
but why can the project file and Make find it?

Building project gnatlib_gtk
gnatmake: objects up to date.
gnatmake -Pgps gps-main.adb
gcc -c -g -gnatec=/home/rlove/gps/gps/gnat_debug.adc -g -O1 -gnata
