Packaging question on MPI requires

I recently packaged up nest[0] which is widely used in the
computational neuroscience research community. The review ticket is
here[1], and the copr builds are here[2]. Even though the rpm builds
perfectly, dnf won't install them from the copr. This is what I get:

> [asinha at cs-as14aho-2-herts-ac-uk  ~]$ rpm -q --provides mpich
> mpi
> mpich = 3.1.4-5.fc23
> mpich(x86-64) = 3.1.4-5.fc23
> mpich2 = 3.0.1
> [asinha at cs-as14aho-2-herts-ac-uk  ~]$ sudo dnf install nest-mpich pynest -y
> Error: nothing provides needed by pynest-2.8.0-1.gitdc21fdc.fc23.x86_64.
> nothing provides needed by nest-mpich-2.8.0-1.gitdc21fdc.fc23.x86_64
> (try to add '--allowerasing' to command line to replace conflicting packages)
> [asinha at cs-as14aho-2-herts-ac-uk  ~]$

Would someone know what I'm doing wrong here? :/
