oldest supported numpy dependency not downloaded for scikit-bio

[RigbeGW]

Hello,

I am using pip2pi to download wheels(and tar) of python packages for offline installation. I used pip2tgz to download scikit-bio and its dependencies but in the offline system the installation of scikit-bio fails with an error "could not find a version that satisfies the requirement oldest-supported-numpy". When I manually download and add the oldest-supported-numpy-2023.10.25.tar.gz, the installation succeeds. It would have been great if pip2pi took care of downloading this dependency.
