Comment (by kencu):

 I used a similar fix to what I did in {{{icu}}}. It is not, perhaps,
 beautiful, or elegant, but it is practical and a minimal change from what
 we have.

 {{{
 % port -v installed libgpg-error
 The following ports are currently installed:
   libgpg-error @1.42_0+universal (active) platform='darwin 20'
 archs='arm64 x86_64' date='2021-05-01T14:22:12-0700'
 }}}
 {{{
  % file /opt/local/lib/libgpg-error.dylib
 /opt/local/lib/libgpg-error.dylib: Mach-O universal binary with 2
 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library
 x86_64] [arm64:Mach-O 64-bit dynamically linked shared library arm64]
 /opt/local/lib/libgpg-error.dylib (for architecture x86_64):    Mach-O
 64-bit dynamically linked shared library x86_64
 /opt/local/lib/libgpg-error.dylib (for architecture arm64):     Mach-O
 64-bit dynamically linked shared library arm64
 }}}

 I'll throw up a PR for critique.
