Comment (by metbic):

 I'm asking this since a simple {{{install python310}}} is not enough to
 install it without universal option.

 As before, I try to install it without universal.

 After typing {{{sudo port install python310}}}, a broken port analysis is
 performed and recommends to rebuild glib2, and in order to do ''that'',
 python310 is automatically installed ''with'' the universal option and
 this again fails.

 Can I somehow instruct the automatic installer to do it without universal?
