python310 @3.10.9+lto+optimizations requires to be rebuilt

[esbugz]

I've tried to install python310 and for some reason instead of just installing the prebuilt option it asks to waste time rebuilding python, although ​https://ports.macports.org/port/python310/details/ says that it should work fine on Catalina (I've tried on 10.15.7)

if you run this:

sudo port -v rev-upgrade

the added "-v" flag will tell you what port is seeing, and why python310 is / is thought to be broken.

This information can be helpful most times to understand what is exactly wrong. Often it might be caused by forcing the uninstall of a dependent port, for example, but there are other reasons it could occur.

Nice, thanks! Fixed via sudo port install openssl3
