I cannot reproduce your problem on my Mojave Mac.

your error log says "xproto.pc" not found. please show me results of the following two commands.

1. port contents xorg-xorgproto | grep xproto.pc
2. pkg-config --debug --exists xproto

results on my Mac:

# [1]
$ port contents xorg-xorgproto | grep xproto.pc
  /opt/local/share/pkgconfig/dmxproto.pc
  /opt/local/share/pkgconfig/xproto.pc

In 6cf3dda10a2afbd7f8bc8b3137c840bd460eb4aa/macports-ports (master):

ruby/rb-rcairo: fix possible build failure

add PKG_CONFIG_PATH to avoild error from missing xproto.pc at configure.
see #57237

[kimuraw (kimura wataru)]

Thanks jpmelko,

I added PKG_CONFIG_PATH into rb-rcairo to solve your error. Try sudo port selfupdate && sudo port install rb-rcairo.

[jpmelko]

It works now

Thanks
