Hello,
I get this:
$ ./script/console
Loading development environment.
/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require’: no such
file to load – readline (LoadError)
…
found a LOT of solutions via google, like
$ apt-get install libncurses5-dev libreadline5-dev
but since I use RedHat this doesn’t work for me.
also tried
$ yum install ncurses-devel readline-devel
without success (ncurses-devel worked, readline-devel failed)
Does anyone know what I could do?
Is it necessary to recompile ruby? 
Thanks in advance,
Paul
