I followed the directions in /inkscape-0.92.3/packaging/macosx/README.txt

The last step "LIBPREFIX="$MP_PREFIX" ./osx-build.sh a c b -j 5 i p -s d” returned the following error messages at the end of the output

Configure failed
Package requirements (cairomm-1.0 >= 1.9.8
 glibmm-2.4  >= 2.28
 giomm-2.4
 sigc++-2.0  >= 2.0.12
 ) were not met:

No package 'cairomm-1.0' found
No package 'glibmm-2.4' found
No package 'giomm-2.4' found
No package 'sigc++-2.0’ found

I captured all of the output to a file if it would help for me to post it somewhere.

How do I fix this?

Also, the link to the Doxyen docs on the website is broken. Safari says it can’t connect to the server.
