Ruby shared libraries on AIX

With Ruby 1.9.1 p376, a simple gem install like "gem install curb" results in a shared library that can not be loaded. The root of the problem is the -Wl,-blibpath:/usr/local/lib argument that is added to the final link.

If you find the rbconfig.rb file down the /usr/local/lib/ruby/1.9.1 path, and find the RPATHFLAG it will be set to " -Wl,-blibpath:%1$-s". Just change it to "" and that will solve the problem.
