if libuuid was present on the system, python would link with it in:
lib/python3.9/lib-dynload/_uuid.cpython-39-x86_64-linux-gnu.so

See merge request nexedi/slapos!1239

Nis module is linking against system library libnsl which is not slapos compatible.

Also note that we use printf instead of echo here because echo behaviour with \n is different with bash or dash.

Currently, we could just list gettext but for maintainability,
it's easier to compare the list with only python&gcc's buildout.cfg

TODO: There are still direct references to specific version of Python in:
  - slapos component
  - bazel templates
  - nextcloud & theia SR
