-I/Library/Frameworks/R.framework/Versions/2.14/Resources/library/RcppArmadillo/include

With all due respect, that is

in the package's DESCRIPTION and
b) confused as you are mixing library arguments and include
arguments (hint: "-lf2c -lm" are useless in CPPFLAGS)

What are talking about? That makes no sense.

Like so many jokes, it will get old by the Nth repetition.
