Help! I have GIMP 2.2. running under SUSE Linux and have downloaded and extracted the help files.

I still get the error "Could not open '/opt/gnome/share/gimp/2.0/help/en/gimp-help.xml' for reading: Permission denied" the folder "en" and the file "gimp-help.xml" do not appear to exist in this (or any)location in the file system. the files '/.congfigure', 'make' and 'make install' which are specfified in the Installation instructuions also do not seem to exist. Can ayone suggest a resolution?
