heroku db:push issue
===

I am having some issues getting db:push to work with heroku.

As I have read else where, there is an issue with ruby versions > 1.9.3-p0, so I've downgraded to 1.9.2-p290, as it seems that that is the most common suggestion.

This can be confirmed via running ruby -v and getting `ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.4.0]`
