 I am running MacOS 11.6.5 (Big Sur) on a 2019 Mac Pro with Intel hardware.
 I have Xcode 13.2.1 installed, and have installed the associated command-
 line tools. I downloaded the MacPorts distribution for Big Sur and ran an
 apparently clean install via the installer. After some searching, I tried:
 "sudo port install gmp" and got the following:

 The log file cited gives a long trace of what happened, but the ultimate
 error is indeed
 {{{
    :error:fetch building gcc46 is not supported with Xcode 9 or greater
    :error:fetch Failed to fetch gcc46: unsupported platform
 }}}
 The advice in the first snipped output, to run "port rev-upgrade" isn't
 very useful:

 I learned a little more about what is actually installed:

 #### SNIP ####
 {{{
 port installed gcc46
 The following ports are currently installed:
  gcc46 @4.6.3_3 (active)
 }}}
 #### UNSNIP ####

 I posted on the GMP mailing list about this with no useful response so
 far.

Comment:

 It looks like gmp installed with no problems. After every install or
 upgrade, rev-upgrade runs automatically, and that checks for broken
 linking in all installed ports. It found that llvm-3.0 and gcc46 are
 broken. You should probably just uninstall those, because they aren't
 going to work on Big Sur anyway.

 The fact that you have those ports installed most likely means your
 MacPorts installation was migrated from an older OS version, and you
 should follow the wiki:Migration procedure.
