 It might be possible that this is a libgpg-error issue (not sure, but in
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_mail_gnupg2/gnupg2/work/gnupg-2.2.39/config.log`
 I see the lines below):
 {{{
 configure:8288: checking for libraries
 configure:8334: checking for gpg-error-config
 configure:8365: result: no
 }}}
 Looking at another system on which I successfully installed gnupg2 before
 (2.2.34), with `libgpg-error @1.44_0`, I see that `gpg-error-config` is
 available at the command line?

 Whatever the cause, it is clear that `configure` fails to detect libgpg-
 error:
 {{{
 configure:16372:
 ***
 *** You need libgpg-error to build this program.
 **  This library is for example available at
 ***   https://gnupg.org/ftp/gcrypt/libgpg-error
 *** (at least version 1.27 is required.)
 ***
 configure:16505: error:
 ***
 *** Required libraries not found. Please consult the above messages
 *** and install them before running configure again.
 ***
 }}}
