 More background: You need to ensure you're using the preferred version of
 `cctools`, which varies depending on the combination of macOS and Xcode.
 Otherwise you'll encounter issues, per the following notes in the
 portfile:

 {{{
 # llvm-11 changed the arguments accepted by llvm-objdump
 # this causes a number of errors in scripts that still use the old
 arguments
 # we will default to +llvm11 when xcode changes to require the new
 arguments
 # see https://reviews.llvm.org/D92310 and
 https://trac.macports.org/ticket/61852
 }}}

 So in short, run `sudo port install cctools`, to ensure you're using the
 preferred version. And then try installing `gegl` again, without trace
 mode.

 Finally, let us know whether all is well, after that's been done.
