Command not working.

[Kunal Goswami]

 Respected Sir/Madam, I am using a macbook pro running os x mavericks version 
10.9.4, I installed octave from the wiki using the home-brew instructions. And 
the problem is whenever I try to use ‘help’ command it displays the following 
error. 

error: unable to open 
/usr/local/Cellar/octave/3.8.1/share/octave/3.8.1/etc/macros.texi for reading
error: called from:
error:   
/usr/local/Cellar/octave/3.8.1/share/octave/3.8.1/m/help/__makeinfo__.m at line 
103, column 5
error:   /usr/local/Cellar/octave/3.8.1/share/octave/3.8.1/m/help/help.m at 
line 99, column 22



 Kindly tell me what to do to resolve it, and use the help command as normal. 
 Thanking you in anticipation, 
Kunal Goswami
