I forgot the following point. TBRIK is a standard ROOT class.
Check that in your .rootrc file you have teh search path for html
including the Root/src directory.
You should have something like:
Root.Html.OutputDir: html
Root.Html.SourceDir: src:include:.:/usr/user/source:/home/brun/root/src
Root.Html.Author: Rene Brun
Root.Html.Root: http://root.cern.ch/root/html
In the second line above, replace /home/brun/root/src
by the directory $ROOTSYS/src
