Comment (by artkiver):

 Added another refactored Portfile.

 Portfile.got0.98.2_defaultstoopensslsortaworks

 Will:

 install OK with %port -v install

 Defaults to OpenSSL(3) but at least picks up the libretls dependency.

 If LibreSSL or libressl-devel are already installed in MacPorts, it might
 also work and use the libressl variant if installed with %port -v install
 +libressl.

 However, there are various caveats:

 e.g. if just installing with no parameters and MacPorts with having
 previously installed install got via %got -v install:
 {{{
 port -vst install
 --->  Computing dependencies for got..
 Error: Can't install libressl because conflicting ports are active:
 openssl
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there is a
 bug.
 Error: Processing of port got failed
 }}}

 Or, cleaning MacPorts entirely via sudo port -fp uninstall installed and
 specifying %port -vst install

 I am still kind of tempted to submit a PR with this version, since %port
 -v install and %port test both seem to function OK and I am guessing it
 will pass GitHub Actions CI as a result?

 Moreover, I think most MacPorts users who use libressl are probably savvy
 enough to be able to work around the potential pitfalls?

 Still, perhaps there is a smarter way to phrase this:

 {{{
 if {[catch {registry_active openssl}] && ![variant_isset libressl]} {
   # openssl is installed and the libressl variant isn't manually
 requested, default to openssl
   default_variants +openssl
 } elseif {([catch {registry_active libressl}] || [catch {registry_active
 libressl-devel}]) && ![variant_isset openssl]} {
   # either libressl or libressl-devel are already installed, and the
 openssl variant is not explicitly requested, default to libressl
   default_variants +libressl
 }
 }}}

 Also, I do NOT for the life of me, understand why if I invoke % port -v
 install +libressl on a clean MacPorts installation it has openssl and
 openssl3 as dependencies?

 e.g.

 {{{
  port -v install +libressl
 --->  Computing dependencies for got...................

  bison
  bison-runtime
  db48
