Odd, maybe that method was introduced in a newer Rails version?

[trekdemo]

Yes, this exists from rails 3.1.0

I dont know what the OPs exact situation is, but I've found that upgrading from 3.0.x to 3.1 is relatively painless. If its the asset pipeline youre worried about, it is optional and defaults to off when upgrading.

[trekdemo]

It's not a critical bug, so i close it.

@shanemcd we have some legacy gems that are incompatible with AR 3.1.x.
But we are planing the upgrade :)
