 You can't run scons by specifying an alternate python version (3.10 here),
 because scons requires its python modules which were installed for a
 specific python version (currently 3.12).

 I see that I was the one who
 [changeset:636bc5899e50c7b8550e4919739a5a1d49502df0/macports-ports made
 this mistake].

 I guess the best we can do is always keep this port using the same python
 version as the scons port. You could add a comment in the scons port
 reminding me that if I switch its python version I need to make the same
 switch in cantera.
