Hi all
I had asked the group about the error: NameError (uninitialized constant
Mysql) appearing on the localhost since last few days.
I was using Webrick for testing. I installed RubyForApache module, which
installed mysql.so along with that. It wasnt successful even after
following documentation/tutorials word-by-word.
Anyway, the bottom line is : I uninstalled RubyForApache and everything
is fine 
May this help if any of you have encountered this problem.
Cheers
Rajesh
