When I try to create that, every time I got same error. What should I do? I saw similar problems but under Ubuntu. They solve it by going some place ...src/ruby../ext/readline and then execute

ruby extconf.rb
make
make install

but I don't see that folder in file system. Why is it all so difficult?

Update

Solved by installing next packages

readline-devel.i686
readline-static.i686

And then making similar operations in the folder ext/readline that placed in downloaded sources of ruby.
