Robin,

Thanks much for the reply.  It turns out, for reasons which are still  
unknown to me, that on this machine, doing the following:

% g++ bessel.cpp   -o bessel -lgsl -lgslcblas

will tell me it can't find -lgsl, in spite of its path being on my  
LD_LIBRARY_PATH.  So, being explicit solves the problem and build the  
executable:

% g++ -v bessel.cpp   -o bessel -L<full-path> -lgsl -lgslcblas

This then gets back to my newbie question -  can I/how can I do a  
similar thing, i.e. manually specify a lib path for R?
