the libs on the system you build on. You may be able to do that by passing
something like --disable-shared to configure, or you can just kludge it and
delete the shared libs after you build and install.

The "not swimming upriver" approach is to look at conda for language
independent cross-platform user level package management :)

It's purpose built to handle the complexities of the scientific Python
stack, while the default Python specific toolchain is more aimed at cases
where you can relatively easily rely on Linux system libraries.
