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.
