CentOS - Feb 2017 - Working on installing mailgraph on Centos7-arm - challenges with rpms

One of the joys with getting a little ahead of where epel-armv7hl is, is 
trying to install packages where not all the dependencies have been 
debugged.

So I am trying to install mailgraph, that i get the noarch rpm from 
Centos7-x86_64.

But it needs RRD which I actually got from the armv7hl building; it just 
did not make it to the repo.

But it wants libpango and libpangocairo.

I can't find what provides those.  They are not anywhere available to my 
Fedora 24 notebook and I don't have any 'normal' Centos7 system
these days.

thanks
