Comment (by cardi):

 Apologies in advance for my lack of Ruby knowledge: I don't use the Ruby
 plugin in WeeChat, but I will help to try to resolve this.

 It looks like WeeChat does automatic detection of the Ruby version
 [https://github.com/weechat/weechat/commit/fe9768f484304c28cf4e6d6eb980613b00ca6904
 (1)] but, AFAIK, the Portfile won't allow us to specify "any installed
 version of Ruby is fine" as a dependency.

 To partially resolve this, I think the following needs to be added to the
 Portfile:
 * add variants for each Ruby version (like [https://github.com/macports
 /macports-
 ports/blob/8888b38c6b866336b94b3956c24a08ea9a008e73/irc/weechat/Portfile#L78-L98
 `python`, `python37`, `python38`, ...])
 * force WeeChat to detect and use the Ruby version the user selects by
 patching `FindRuby.cmake`
 [https://github.com/weechat/weechat/blob/3e8580b5e554b06c6754dfedee933494d6af0c08/cmake/FindRuby.cmake
 (2)] in a similar way to [https://github.com/macports/macports-
 ports/blob/8888b38c6b866336b94b3956c24a08ea9a008e73/irc/weechat/Portfile#L100-L112
 Python]

 Re: the other issues (`-lx86_64` and `-L/usr/local/opt/ruby/lib`), I'll
 have to debug the build to see if I have these issues on my side as well.
