I've gone through the gems 68 and 69 here:
http://www.adacore.com/adaanswers/gems/gem-68/
http://www.adacore.com/adaanswers/gems/gem-69/

I was able to reproduce the examiner/simply/POGS results, but if I actually=
 try to compile the code from GPS, I get the message:
  gprbuild -d -P/Users/Dependable/Tools/Spark1/search/default.gpr
  default.gpr:1:09: warning: no compiler specified for language "Ada", igno=
ring all its sources
  gprbuild: no sources to compile
Similarly, if I try to compile just search.adb, I get:
  gprbuild -ws -c -u -P/Users/Dependable/Tools/Spark1/search/default.gpr se=
arch.adb
  gprbuild: "search.adb" is not a source of any project

If I go to Project->Edit Project Properties, I see that Ada is checked as a=
 language, and its compiler is set as gnatmake. The file default.gpr looks =
like:
=3D=3D=3D=3D
project Default is

--   for Languages use ("Ada");

   package Ide is
      for Default_Switches ("examiner") use ("-index_file=3Dsearch.idx", "-=
config=3Dsearch.cfg", "-flow_analysis=3Ddata", "-vcg");
--      for Compiler_Command ("ada") use "gnatmake";
   end Ide;

   package Compiler is
      for Default_Switches ("ada") use ("-g", "-O2");
   end Compiler;

end Default;
=3D=3D=3D=3D
With the lines commented out with "--" having no impact whether they are co=
mmented out or not (since these are the default values).

I'm using the native gnat toolchain, version GPL 2011 (20110419), and my GP=
S version is GPS 5.0.1 (20110113) hosted on x86_64-apple-darwin10.2.0. I'm =
on OS X 10.6.8. I was able to compile in GPS a couple days ago, so I feel l=
ike something's changed (although I haven't updated any software since then=
), but I have no idea what.

Any help would be appreciated.

Thanks,
-Ben
