No -- this isn't a CPAN Testing framework problem.  It's a Makefile.PL
and Module::Build::Compat problem.

If you look at the test report, you see this:

Output from '/home/src/perl/repoperls/installed-perls/maint-5.8/p8tnrrm/perl-5.8.0@27144/bin/perl
Makefile.PL':

So here's what I think happens:

1. Makefile.PL runs M::B::Compat, which runs Build.PL, which exits
with 0 and doesn't create a Build file.

2. M::B::Compat doesn't check if a Build file was created -- it only
checks to see if Build.PL ran without error -- and "exit 0" is not an
error.

3. M::B::Compat writes a Makefile and therefore CPAN.pm decides that
Makefile.PL was successful and continues instead of stopping.

The last line of the Makefile.PL just needs to test for the presence
of a "Build" file:

  Module::Build::Compat->run_build_pl(args => \@ARGV);
  Module::Build::Compat->write_makefile() if -f "Build";
