irr crashes on Rails 2.3.8

Me again. I have a strange performance issue on Ruby 1.9.3p194 with Rails 2.3.8. When I run a simple calculation of irb to limited set of cashflows on irb, it works fine.
But when i'm running ./script/console or in the app itself, .irr takes infinutum time and crashes the app server.

In the Rails app, I include the gem in the Gemfile and include the finance Module on the class.

Thanks in advance.

Problem solved.

Every member of the input array to compute the IRR must be converted to Flt::DecNum type

@c-castillo I had no luck with using Flt::DecNum. I know this has been AWHILE, but I'm very curious if you've dealt with a similar performance issue and tried a different approach. thanks!
