	ruby-2.1.1_1,1                 lang/ruby21
	readline-6.3_1                 devel/readline

>Description:
	Ruby 2.1 fails to build in it's readline extension, as it still uses
	the very-old-style "Function" type (instead of rl_hook_func_t).
	This does not affect ruby 1.9 nor ruby 2.0.
>How-To-Repeat:
	
>Fix:
	Patch obtained from upstream:
	http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/ext/readline/readline.c?r1=43458&r2=45225
