Comment (by skymoo):

 Replying to [comment:2 cjones051073]:
 > libgcc8 now provides the default gcc runtime, via libgcc. Both thus
 intentionally conflict with libgcc-devel which is now based on gcc9.

 So we can no longer have the development version of `gcc` installed if we
 want stable versions as well?

 > I suggest you (forcibly) uninstall your current gcc ports, then
 reinstall them back. If you want to be able to use gcc9 you will need to
 first install this, so that libgcc-devel is installed before libgcc is.

 That's what I currently have, I installed `libgcc-devel` and then the
 other `gcc` ports. `libgcc-devel` is updated before attempting to install
 `gcc8`. Also this seems to conflict with your first statement?
