 I get this error when running `git gui`:

 {{{
 macOS 11 or later required !
 error: git-gui died of signal 6
 }}}

 And when running `gitk`:

 {{{
 application-specific initialization failed: couldn't connect to display
 ":0"
 Error in startup script: couldn't connect to display ":0"
     while executing
 "load /opt/local/lib/libtk8.6.dylib Tk"
     ("package ifneeded Tk 8.6.10" script)
     invoked from within
 "package require Tk"
     (file "/opt/local/bin/gitk" line 10)
 }}}

 They were working fine, seemed to have started happening after a recent
 update.
