info files

[Phil Spector]

I just installed version 0.77 for my Sparc Station.  I am using a
directory other than /usr/lib for the octave home directory, and
have set up the directories as outlined in the doinstall.sh script -
in particular, I've made links from the files 
   $OCTAVE_HOME/doc/octave.info*
into the directory $OCTAVE_HOME/info.  
Inside of octave, the normal help files are fine, but the -i option
doesn't work:

   octave:1> help mean
   
   *** mean:
   
    usage: mean (a)
   
    For vector arguments, return the mean the values.
   
    For matrix arguments, return a row vector containing the mean for
    each column.
   
    See also: median, std
   
   
   Additional help for builtin functions, operators, and variables
   is available in the on-line version of the manual.
   
   Use the command `help -i <topic>' to search the manual index.
   octave:2> help -i mean
   warning: can't find info file!
   
   help: sorry, `mean' is not indexed in the manual

How can I set up the info files so that octave can find them?      - Phil
