Ok, after some ib_srpt magic with  __udivdi3, I finally got it inserted into
my kernel. I'm not real familiar with srpt. If I look
at /sys/kernel/scst_tgt/targets/ib_srpt/, I see nothing there so scstadmin
complains that target ib_srpt_target_0 doesn't exist. I'm assuming I need
InfiniBand hardware. It's going to be difficult figuring this one out.

Can you give me the directory structure
under /sys/kernel/scst_tgt/targets/ib_srpt/ ?
