Unable to install on USS

Describe the bug

Attempted to install the SDK on my USS environment, but the install fails.

Expected and actual results

Expected a clean installation, but ended up with an error during the build process.

An excerpt from the install messages. Appears to report "Unsupported platform: 314". See below..

Describe your environment

IBM Open Enterprise SDK for Python 3.14.0.1
pip 25.2 from /usr/local

z/OS 2.5 USS
Bash shell

Additional context

Start by reproducing the SDK installation on z/OS USS with IBM Open Enterprise SDK for Python 3.14 and pip, then inspect the maturin metadata failure reporting SOABI cpython-314 and "Unsupported platform: 314". Done means the SDK installs cleanly in the reported environment without the build-dependency error.
