Description of problem:
Installing rubygem-ditz also installs rubygem-trollop. After
this, for example (with ruby-ri installed)
$ ri Trollop::Parser#opt
shows:
---------------------------------------------------------
More than one method matched your request. You can refine
your search by asking for information on one of:

     Trollop::Parser#opt, Trollop::Parser#opt
----------------------------------------------------------
i.e. there are two Trollop::Parser#opt ri manuals installed on
     the system, which should be one.

Version-Release number of selected component (if applicable):
rubygem-trollop-1.15-1.fc12.noarch
rubygem-ditz-0.5-4.fc12.noarch

How reproducible:
100%

Steps to Reproduce:
1. yum install ruby-ri rubygem-ditz
2. ri Trollop::Parser#opt
3.
  
Actual results:
see above

Expected results:
$ ri Trollop::Parser#opt should return Trollop::Parser#opt manual.
With only rubygem-trollop installed, this returns:
+++++++++++++++++++++++++++++++++++++++++++++++
---------------------------------------------------- Trollop::Parser#opt
     opt(name, desc="", opts={})
------------------------------------------------------------------------
     Define an option. +name+ is the option name, a unique identifier
     for the option that you will use internally, which should be a
     symbol or a string. +desc+ is a string description which will be
     displayed in help messages.

Additional info:
This is because rubygem-ditz-0.5-4.fc12.noarch rpm also installs
ri manuals for Trollop (under
/usr/lib/ruby/gems/1.8/doc/ditz-0.5/ri/Trollop ).
I should have noticed this issue on the review...

Note that until recently ri command was completely broken for ri manuals
installed via gem (see bug 528787). Fixed ruby-ri is available on
the newest F-12 rawhide / F11-updates-testing.
