As it seems to break at the space, escaping those seems to help:

edd@basebud:~/src/debian/CRAN/tseries-0.10-3/src> MAKEFLAGS='CFLAGS=-g\ -O2\ -Wall' R \
CMD SHLIB *.c gcc -I/usr/share/R/include -I/usr/share/R/include     -fpic  -g -O2 \

Using bash on Debian.  Does that work for you on Mac OS X too?
