Yes, but it does not happen if I run 
.../bin/R --vanilla < .../R-1.1.0/tests/Examples/base-Ex.R
from a directory of my home area in the network.
Now it seems to me that I did not get all rights properly from our system 
administrator to perform "save" and "load". So it seems to be a problem of
our network, and not of R. 

Is there a way to perform the whole check from another directory?

make /usr/applic/packages/R/R-1.1.0/bin/check
yields
make: Nothing to be done for `/usr/applic/packages/R/R-1.1.0/bin/check'.

Or have I already performed everything by .../bin/R --vanilla on base-Ex.R?

install.packages("mclust") on July 15th. I should have the current mclust,
shouldn`t I?
Perhaps it is because SuSe 5.2 is too old for that?

FLIBS =  -lf2c -lm -L /usr/X11R6/lib -L/usr/lib/gcc-lib/i486-linux/2.7.2.1 -L/usr/i486-linux/lib -lm

Thank you for help,
