Since I'm using the 'gem' from inside my Locomotive bundle, I would
expect it to update gems there.. not somewhere else.. but yes that might
be an incorrect assumption.
% which gem
/Applications/Locomotive2/Bundles/standardRailsSept2006.locobundle/i386/bin//gem
% gem list -d activerecord
*** LOCAL GEMS ***
activerecord (1.15.0, 1.14.4)
Implements the ActiveRecord pattern for ORM.
This seems to imply that was updated, doesn't it?

Given that it seems that 1.15 is present, how do I affect which one gets
used?

I'm using the mysql adapter. It worked well enough to get through the
first migration (creating the relevant table and the first columns). I
have no way of identifying what types the adapter supports, other than
possibly trying a bunch of things.. but that only tells us something if
the adapter is working as expected (which it might not be).

Changing :decimal (from the example) to :float allows the migration to
proceed. I'm not sure what information to take from that.. is this
because the wrong version of activerecord is being used, and :float has
been replaced with :decimal in 1.15? Is it because there's something
wrong with the mysql adapter and only one of the two works? It seems
like there could be a half-dozen different reasons for that, and I'm not
sure which way to go in order to make my install conform more closely to
what's expected by the book.
