 ## Install ccache
 
+AIX72: TODO describe how to install with curl
+
+  The right way to do this is not with CC and CXX that have ccache in them,

 Install ccache based on these instructions ./setup/ansible-tasks/ccache.yaml,
 we should update that script so that it can be used on AIX as well.
 Install on the new linux machines did not seem to work so use cp and chmod instead.
