[El] Did I just make a lot of work for myself or is there an easy way out?

This is not correct. The various ELGIS repositories are built only
against Base and EPEL.

When going the rebuild way, I rather recommend to use mock (from
CentOS, not from EPEL!). This is worth the little investment to set it
up.
