>Description:
RDoc 3.6 is still compatible with ruby 1.8, although it was lately marked as BROKEN for ruby 1.8. The NetBSD guys have fixed the problem for pkgsrc:

http://comments.gmane.org/gmane.os.netbsd.devel.pkgsrc.cvs/157338
>How-To-Repeat:
Try to install devel/rubygem-rdoc while having ruby 1.8 installed.
