Hi Mazembo Whatever your problem with gems may be, I cannot imagine ever using different versions of Ruby in development versus production (at least major version differences like 1.9 and 2.0). That sounds like a bad tradeoff, just to use some gem. I would find another way to use that gem or find an alternate gem. And as a last resort, I would consider hand-coding my own solution before I would use different versions of Ruby between dev and production.
Per your asset compilation problem... Try running the asset pre-compilation with the --trace flag and perhaps post those results on this thread.
