$ cat src/Makevars
PKG_LIBS = -lzmq
PKG_CFLAGS = -I/usr/local/zmq

$ ls src
Makevars	interface.cpp	interface.h

$ R CMD INSTALL --build .
* installing to library
‘/Library/Frameworks/R.framework/Versions/2.14/Resources/library’
* installing *source* package ‘rzmq’ ...
** libs
*** arch - i386
g++-4.2 -arch i386 -I/Library/Frameworks/R.framework/Resources/include
-I/Library/Frameworks/R.framework/Resources/include/i386
-I/usr/local/include    -fPIC  -g -O2 -c interface.cpp -o interface.o
interface.cpp:20:19: error: zmq.hpp: No such file or directory
...
