Comment (by kencu):

 gcc10 is not as yet supported in MacPorts on < 10.6 as all the work needed
 to integrate it (or even get it to build smoothly) has not been done yet.
 Perhaps someday it might be, if someone like you gets enthusiastic enough
 and does it !

 Until gcc10 is available in MacPorts, eg by doing this:

 {{{
 sudo port -v install gcc10
 }}}

 the ban must stay.

 Aside:

 Looking at that block, it looks like gcc9, 10, and 11 are banned on
 os.major < 12.

 If that is true and I'm reading that correctly, note that all gcc
 compilers build on os.major 10 and 11 for a year or so now, so that might
 be out of date.
