Port reclaim unexpectedly wants to uninstall a subport, when the top level port is installed

> I'm puzzling over some weird "port reclaim" behaviour on one machine.  On the problematic machine, I installed py-matplotlib, which correctly installed py312-matplotlib.  But, if I run "port reclaim", it wants to uninstall py312-matplotlib as a "Unrequested ports without requested dependents found".

Possibly you had previously installed py-matplotlib when an older python 
version was the default? In any case, running 'sudo port upgrade 
py-matplotlib' will refresh its registry data.
