 Building Mono packages should come from the `mono' tarball.

 The fact that the runtime SIGILLs on every CPU except the G4 is 
 quite obviously a bug _in the runtime_.

+Ulrich, we agree there is a bug in the runtime, though it's not really
+specific to the non-G4: I regularly test on a double G5, though
+running under macosx. It would be useful if you can run mcs in the
+runtime and report the instruction address where the SIGILL happens:
+disassemble that point and a few dozen instructions before and after
+(run with mono -v so we can see which method the IP belongs to).
+The cache hint may be helpful, too: could you try changing
+MIN_CACHE_LINE in mono/mono/mini-ppc.c to 4 (from 8), recompile and
+retry? You may also want to try mono from cvs: there were a number of
+updates since the release.
