Is there some new trick to making raid devices on Centos5?

# mdadm --create /dev/md3 --level=1 --raid-devices=2 /dev/sdc1 /dev/sdc1 mdadm: error opening /dev/md3: No such file or directory

Hmm, is that a typo? You have /dev/sdc1 twice in the above command.

Yes but the typo happened when I retyped the line the 2nd time. The first time had /dev/sdd1 as the 2nd entry and had the same result. It turns out --auto=yes is the magic option to make it work as Ross Walker pointed out in another reply.
