Just for the record, modify Makefile.in:
NVCC_FLAGS = -c -Xptxas -v -fmad=true -arch sm_10
to
NVCC_FLAGS = -c -Xptxas -v -fmad=true -arch sm_32
and then ./configure --disable-mpi && make -s worked for me.
sm_20 seems to be enough to compile john, but with sm_32 you will likely
get better performance.
Example for phpass-cuda format:
sm_20:
Raw: 110276 c/s real, 110276 c/s virtual
sm_32:
Raw: 126030 c/s real, 127117 c/s virtual
