Thank you troy for your answers. Yes i will try this and also I just 
found the 5.5 iso I saved a year agao and will use it as I lost my 
5.5 dvds I burn a year ago.

Do you advise us to use sl6 instead or is too early to use it .... as we 
will use our linux linux boxes for a research collaboration and we need 
all the programs run well there.
