Can't mount shared directory

[mc0e]

I've had a whole heap of trouble getting started, that turned out to be because the underlying vagrant box is long out of date, and doesn't support the current version of VirtualBox Guest Additions.

The fix for the VirtualBox Guest Additions bit turns out to be quite simple. Just do a sudo yum update inside the vagrant box and then a vagrant reload from outside. However it doesn't end there. Having done those updates, I get further errors:

That seems to come from trouble installing the postgis-postgresql95 package.
