WHen libyaml is not installed, make fails with the following cryptic message: ``` gmake[2]: Entering directory '/home/chkbuild/chkbuild-crossruby/tmp/build/20220325T045825Z/ruby/ext/psych' gmake[2]: *** No rule to make target 'yaml/yaml.h', needed by 'psych.o'. Stop. gmake[2]: Leaving directory '/home/chkbuild/chkbuild-crossruby/tmp/build/20220325T045825Z/ruby/ext/psych' ``` I think it should give up building psych with a clear message.
