Installing the Mojo SDK fails

I'm trying to install the Mojo SDK on a Linux server running Debian 12. I have successfully installed the modular package. When running modular install mojo, it seems that the installer is trying to install a pip-install a site-wide python-package(!?), as I'm getting this error:

# Found release for https://packages.modular.com/mojo @ 0.2.1, installing to /home/hoyma/.modular/pkg/packages.modular.com_mojo
# Downloads complete, setting configs...
# Configs complete, running post-install hooks...
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

# Found release for https://packages.modular.com/mojo @ 0.2.1, installing to /home/hoyma/.modular/pkg/packages.modular.com_mojo

error: externally-managed-environment

    install.

Using pip to install system-wide packages is not a good thing, as described in PEP 668. I'm using pyenv and pyenv-virtualenv, so I would much rather install the Mojo SDK in an isolated virtual environment with a suitable Python-version. How can I do that? I've tried to create a virtual environment and activate it before running modular install mojo, but that didn't help.
