# Apache::Reload, Apache::SizeLimit, and Apache::Test are force-unbundled.
# The minimum versions requested here are the bundled versions.

# The test dependencies are from CPAN (Bundle::Apache2).

# When all MPMs are disabled via useflags, the apache ebuild selects a
# default one, which will likely need threading.
