I've been sitting on the attached patch against CPANPLUS::Dist::Build 
for a while because 1) I'm not knowledgeable about CPANPLUS to know how 
to properly test it; and 2) it still has the problem of suspending 
output until the test completes before sending to stdout.

I thought maybe I could extend the patch a little further to use IO::Tee 
to eliminate the delayed output, but it doesn't seem to work:

#!/usr/bin/perl

use File::Spec;
chdir( File::Spec->catdir( glob('~'), 'Module-Build' ) );

use Module::Build;
my $mb = Module::Build->new_from_context;
$mb->dispatch('build');


require IO::String;
my $io = IO::String->new;

require IO::Tee;
my $tee = IO::Tee->new(\*STDOUT, $io);


my $SAVE_OUT = select($tee);

$mb->dispatch('test', test_files => 't/runthrough.t', verbose => 1);

select($SAVE_OUT);


my $result = ${$io->string_ref};
# craft a report from $result . $@

__END__


This works fine when tests succeed, but when there is a failure in the 
test...

# Looks like you failed 1 test of 33.
dubious
         Test returned status 1 (wstat 256, 0x100)
DIED. FAILED test 1
         Failed 1/33 tests, 96.97% okay (less 4 skipped tests: 28 okay, 
84.85%)
Undefined format "Symbol::GEN128" called at 
/usr/share/perl/5.8/Test/Harness.pm line 542.


Anyone know how to make this work, please?

Randy.
