Hello,
building OpenCPN in pkgsrc-2019Q3 fails with:
In file included from /usr/tmp/geography/opencpn/work/.buildlink/include/pango-1.0/pango/pango-font.h:25:0,

 #include <hb.h>
          ^~~~~~

This file is in ./include/harfbuzz/hb.h in /usr/pkg and in the buildink
directory. In 2019Q2 pango-coverage.h doens't #include this file.

What's the best way to fix this ? Add -I/usr/pkg/include/harfbuzz to CFLAGS in
OpenCPN, or change fix pango to #include <harfbuzz/hb.h> instead ?
