Thanks to you for your help.  Following your guidance,  kdeedu-4.4.5  now 
builds successfully against R-2.11.1.   However when I    edit ~/etc/ldpaths 
with  the line

export LD_LIBRARY_PATH=path/to/acml/lib:$LD_LIBRARY_PATH

R fails to start.  it only starts when   the above point to $R_HOME/lib. (nb I 
have  a symbolic link of libacml.so  to libRblas.so
any ideas?
