Subject: Re: Console output formatting

RubyDL looks like it would work but can't find any good docs. Here is 
what I got down.

require 'dl'
me = ""
clib = DL.dlopen("libc.so.6")
message = "Hello\n"
printf("Testing: %s", message)
clib.scanf("%s", me)
printf("danrn, %s!\n", me)
puts message

running in irb i get no errors loading but the printf throws an error if 
I put clib. in front of it.  The scanf gets throws an error also. I know 
I am doing something incorrectly but I don't know what.  Thanks for your 
help and info.
