[R-SIG-Mac] bug in rattle installation ?

[Sid Touati]

Dear rattle users on mac os 10.5.6
I am trying to install rattle on my mac os 10.5.6
I followed all the installation steps in the webpage on rattle. However 
the execution has problems:

X11 is already installed on my system
X11 is launched before lauching the R command line, and this does not 
solve the pb.

We would appreciate any help.
