yahoofinance (1.2.2)

[lsansonetti@…]

I was able to install the yahoofinance gem using trunk

$ sudo macgem install yahoofinance

So I suspect your macgem update --system line introduced these problems. I will look at the newest version of RubyGems and see if it also work with MacRuby.

In the meantime, it is preferable to not upgrade RubyGems and keep the version that ships with MacRuby.
