Well, after several permutations, I believe the magic string was:
export CPPFLAGS='-I/usr/local/include'
Near as I can tell, double quotes, CFLAGS, and CPATH were all
failures, but I ain't the expert in these matters. Novices replace
'export' with 'setenv' if they are on csh instead of bash, right?
Anyway, thanks for all the replies - now to start reading that
