Comment (by mojca@…):

 Just to make it complete, here's what I get on 10.6 (YAY!!!):

 {{{
 root [1] new TBrowser();
 root [2] .demo
 /opt/local/libexec/root6/share/doc/root/tutorials/demos.C:10:12: error:
 redefinition of 'dirName'
    TString dirName =

            ^
 /opt/local/libexec/root6/share/doc/root/tutorials/demos.C:10:12: note:
 previous definition is here
    TString dirName =
 gSystem->UnixPathName(gInterpreter->GetCurrentMacroName());
            ^

 }}}

 If I go to `/opt/local/libexec/root6/lib` then it works, but `hsimple`
 would crash with:

 {{{

 and lots of crashing with different demos.

 These were example I meant with "`port test`", even though it's kind of
 difficult to test graphical examples.
