Well, this is a fresh install of the OS - so, 0.53 has never existed
on the system.  So not sure how there could be a version mismatch.

Anyways, after having trouble with installing 0.6 locally - I decided
to go back and just install 0.5, but I am still encountering
(different) problems.

I will start a new and separate thread.
