The second software update for Mac OS 10.5 Leopard, named 10.5.2, has just been released.
RubyGems has been updated to 1.0.1, and RubyCocoa to 0.13.1, which are both respectively the latest versions available.
A problem was fixed in the Ruby rbconfig.rb’s LDSHARED variable, which didn’t include “-undefined dynamic_lookup”, and caused some 3rd party libraries like RubyInline to fail. Note that RubyInline shipped a fix quite early.
Enjoy, and report bugs as usual!
