Comment:

 gcc7/libgcc7 is not (currently) supported in macOS 10.15.

 Your ports cannot be up to date as you should have received the message.

 {{{
 Error: gcc7 7.4.0 is (currently) not supported on Darwin 19
 Error: See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90835 for more
 details
 Error: Until the issue is addressed in Xcode, please instead install gcc9
 / libgcc9
 Error: Failed to fetch libgcc7: incompatible OS X version
 }}}

 Please run

 {{{
 sudo port sync
 }}}

 then follow the advice in the above ticket, and use gcc9 instead.
