hanna --gems fails with 1.9.2

[Quintus]

The command to generate gem docs for all installed gems, hanna --gems, fails on 1.9.2 since hanna tries to document rdoc, rake and minitest, which don't behave as normal gems. Example session on a freshly compiled Ruby (no gems installed):

    marvin@ikarus:~$ sudo gem install --no-rdoc hanna
    Successfully installed rdoc-2.3.0
    Successfully installed haml-2.2.24

Hmm I didn't know that. How are these "system" gems different?

Thanks for reporting this

[Quintus]

They don't reside in the gems/ directory, but rather directly in the stdlib. Again, on a freshly compiled Ruby:

marvin@ikarus:~$ gem list

*** LOCAL GEMS ***

minitest (1.6.0)
rake (0.8.7)
rdoc (2.5.8)
marvin@ikarus:~$ ls -a /opt/rubies/ruby-1.9.2-p0/lib/ruby/gems/1.9.1/gems
.  ..
marvin@ikarus:~$ gem which rake
/opt/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/rake.rb
marvin@ikarus:~$

i think this works with my fork, if not, please let me know.

Hm, I just downloaded it from your master repo, but it doesn't work:

marvin@kerberos:~$ sudo gem list --local

I previously uninstalled the old hanna gem to avoid possible conflicts.
