description		Powerful and clean object-oriented scripting language
long_description	Ruby is the interpreted scripting language for quick \
					and easy object-oriented programming. It has many \
					features to process text files and to do system \
					management tasks (as in Perl). It is simple, \
					straight-forward, extensible, and portable.

# vendordir: enable vendor-specific.rb
# #3604: gcc4 fails to detect linking at configure
# #19050: use $(CC) not cc, this change has been merged at ruby-1.8 trunk
# #15528: on some Mac, TCPServer.open("localhost", 0) raises SocketError
#         like "getaddrinfo: nodename nor servname provided, or not
#         known (SocketError)"
# c99: gperf generates code that doesn't work with clang (https://trac.macports.org/ticket/29974)
# lib-drb-ssl.rb: 512bits rsa key is too small for openssl-1.0.1.
#                 (http://bugs.ruby-lang.org/issues/6221)
# --- clang support ----
# numeric.c: fix wrong optimizaton of Numeric/Bignum build with clang.
# configure: correct frame_address and stack_direction for +universal with clang.
