It is somewhat similar but still different from OS X Lion, Attempting Nokogiri install - libxml2 is missing and An error occurred while installing nokogiri (1.5.2)

Thanks in advance.

Answer 1

i solved the problem by reinstalling ruby using the following Gist: gist.github.com/1856859 . A friend pointed out that the --with-gcc=clang option during install is important for Lion/Snow Leopard

Answer 2

There is a minor issue in configre.in of stock ruby-1.9.3-p125. You may try using latest head of RVM as mentioned in " Issue updating Ruby on Mac with Xcode 4.3.1"

Other module may fail due to dynamic linking.
