Rodney is correct here, Doug. The ':' makes it use this only iff no value has
been set. So 'our' systems don't have it:
edd@max:~$ grep "^CPPF" /etc/R/Makeconf
/usr/local/lib/R-devel/lib/R/etc/Makeconf
/etc/R/Makeconf:CPPFLAGS =
/usr/local/lib/R-devel/lib/R/etc/Makeconf:CPPFLAGS = -I/usr/local/include
because
edd@max:~$ grep CPPFL src/debian/R/R-2.15.1/debian/rules
CPPFLAGS= \
edd@max:~$
I tell the Debian build to use an empty CPPFLAGS (and that setting has
probably been like that for many years). My own local build of R-devel
has it set because I didn't override it.
