ruby20: warnings from library files that differ only by case of filename

[Polyergic (Shad Sterling)]

It looks like there's at least one library file that shouldn't be there

executing this code:

#!/opt/local/bin/ruby -wU
require "Digest"
Digest::MD5.digest("!")

generates this output"

I think this is not a problem of port:ruby20. the cause of this warnings is OS X's default filesystem called "HFS+".

• HFS+ is a case insensitive filesystem.
  • type LS in terminal.app then runs ls. that does not mean executable file named "LS" exists.
• port:ruby20 contains only "digest.rb".
• you should code require "digest" not "Digest".

% port contents ruby20 | grep -i 'digest\.rb'
  /opt/local/lib/ruby2.0/2.0.0/digest.rb
  /opt/local/lib/ruby2.0/2.0.0/openssl/digest.rb
  /opt/local/lib/ruby2.0/2.0.0/webrick/httpauth/htdigest.rb

Huh, I guess I lost track of which language uses which capitalization convention for require/import/use/include/etc, and didn't notice the examples used all lower case. Not sure why Digest was the only module affected. Thanks.
