After a long sufferance  I had succeeded in installing R GUI on my
Linux/SuSE system. It worked fine.
Unluckily a system upgrade patch messed up my monitor so I had to reinstall
SuSE 10.3 and every other application on top of it.
I have R running back with text interface. I tried to get the nice R GUI  up
& running again. I followed all the steps to reinstall the R GUI but this
time I get a list of errors that I cannot remember seeing on my previous
installation. In the following I have pasted the main steps and messages.
Any suggestion how to solve this installation problem is welcome.

Thank you in advance,
Maura
