How reconcile openmodelica-dvel & octave dependencies on sundials vs. sundials2

[Ken Cunningham]

Welcome to our world!

How to fix this?...

you could try using sundials in octave (change the dependency in the Portfile). Maybe sundials2 was just an oversight. If that works, come up with a variant.

you could disable sundials in octave if you don't want or need it (again, maybe a variant).

But, the upgrade of octave to 4.4 requires the sundials2 port (2.7.0).  So, somehow it seems that upgrading octaves requires downgrading sundials.  But, that is not compatible with openmodelica).

This can be easier as most ports don't need to be modified, but also can generate hassles if the wrong library or header collection is found.
