../run/john --test --format=md5crypt-opencl

I've installed hashcat, and it hangs for 30min+ on a test of the same format. So, no.
Can you suggest any other program? Or is this negative result sufficient to show that, I suppose, OpenCL on the system, with or without pocl (which I installed subsequently), is somehow deficient?

I cloned from github ~18hrs ago.
My procedure follows.
apt-get install ocl-icd-libopencl1 clinfo libopenmpi2 openmpi-bin argon2
The following additional packages will be installed:
libgfortran3 libhwloc-plugins libhwloc5 libibverbs1 openmpi-common
an installation of rexgen followed by running ldconfig, and then,
git clone git://github.com/magnumripper/JohnTheRipper -b bleeding-jumbo john
apt-get libssl-dev yasm libgmp-dev libpcap-dev libbz2-dev zlib1g-dev libopenmpi-dev openmpi-bin libgmpxx4ldbl libpcap0.8 libpcap0.8-dev libhwloc-dev libibverbs-dev libltdl-dev libnuma-dev opencl-c-headers libzip-dev libzip4
cd john/src
./configure --enable-mpi
make -s clean && make -sj6
../run/john --test=0 --format=cpu
Testing: crypt, generic crypt(3) [?/64]... (6xOMP) PASS
All 404 formats passed self-tests!
Incidentally, I am working on a Rock Pi. When I run the binary compiled on a Rock64, I see,
All 705 formats passed self-tests!
When I compile from the (older bleeding) source for this JtR, I see
All 403 formats passed self-tests!
Why am I seeing different quanties of formats?
