This error is "cannot find system.ads" - first make sure your RTS 
directory contains adainclude/system.ads, and then figure out why the --
RTS= option is ignored/wrong/broken.

As of a couple of revisions ago, some tools (FSF tree, gnatclean+?) were 
looking for system.ads in the wrong place (ignoring --RTS) but that 
didn't affect normal builds.

As a crosscheck, have you tried building with gnatmake and a direct 
command line (no gpr), which DOES honour the --RTS= option? This may 
yield some light on what's wrong.
