Comment (by herbygillot):

 @haraldgroven thanks for your patience on this.

 I've installed the dependencies you listed in a fresh 10.14 environment
 and was able to successfully build MySQL 8 alongside 5.7 again, so
 unfortunately I am again unable to reproduce this issue.

 Looking at the log again:

 {{{
 :info:build make[2]: *** No rule to make target
 `/opt/local/lib/libsasl2.dylib', needed by
 `plugin_output_directory/authentication_ldap_sasl_client.so'.  Stop.

 }}}

 ...this is definitely weird.  Even after the dependency install and build,
 I don't see a copy of **libsasl2.dylib** in the Macports tree
 (**/opt/local/lib**).  This seems to be a macOS system lib, found in
 **/usr/lib**, so the build process trying to either find or build it in
 **/opt/local/lib** is abnormal.

 You mention you are uninstalling and reinstalling MacPorts - did that
 include removing your prior MacPorts tree? ie., did you delete
 **/opt/local** as part of the uninstall process?  That might be a bit of a
 hassle, but I think doing that would be a proper clean reset.  You will
 probably want to backup configuration files you care about from
 **/opt/local/etc** and data from **/opt/local/var/db** beforehand.

 The MacPorts official guide actually recommends an even more thorough
 process:

 https://guide.macports.org/chunked/installing.macports.uninstalling.html

 I wish I had a better suggestion, but as I am unable to reproduce the
 issue, I think it's worth trying a full MacPorts reset to see if the issue
 still persists afterwards.
