How do you redefine your search in the following instance?
$ ri File#path
More than one method matched your request. You can refine
your search by asking for information on one of:

      File#path, FileUtils#mkpath, File#path
$ ??
$ ruby -v
ruby 1.8.2 (2004-07-29) [powerpc-darwin7.5.0]
#########
File#path is not the only time this happens, for example String#unpack 
leads to the same situation.
I am using ri in bash with the following alias:
# ri alias
alias ri='ri -T'
##
I installed ruby from source using $./configure --enable-install-doc; 
make; sudo make install
The only other ruby package I have installed is racc.
