I am using OSX Yosemite (10.10.3), and when I try to install cupertino via gem using "gem install cupertino" I get the following error. What can I do to correct this. I have tried many solutions I have tried online to no avail.
libxml2 is missing. Please locate mkmf.log to investigate how it is failing.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers
