I'll answer these in reverse:

2) See http://perl.apache.org/docs/2.0/devel/testing/testing.html
Though you can really rely on it once Apache::Test is released, which 
will happen when mod_perl 2.0 is released.

1) That's an interesting problem. It seems that nobody has asked this 
question before. Here is my take on it. If you like this solution I'll 
add it to the docs.


Makefile.PL
-----------
use ExtUtils::MakeMaker;

# set prerequisites
my %prereq = (
    Foo => 1.56,
);

# Manually test whether Apache::DBI is installed and add it to the
# PREREQ_PM if it's not installed, so CPAN.pm will automatically fetch
# it. If Apache::DBI is already installed it will fail to get loaded by
# MakeMaker because it requires the mod_perl environment to load.
eval { require Apache::DBI };
if ($@ && $@ !~ /Can't locate object method/) {
    $prereq{Apache::DBI} = '';
}

WriteMakefile(
    NAME                => 'Apache::SuperDuper',
    VERSION_FROM        => 'SuperDuper.pm',
    PREREQ_PM           => \%prereq,
    # ...
);
