OK dev/ammo42,

  I'll try strace once I figure out how. Tim, in the mean time, I have rebuilt
all the x86_64 packages and I have captured a full debug of the issue with gdb.
Here is it:

  If you have a command line you would like me to run with strace, I'll take it,
otherwise, I'll report back with what I come up with. I hope this helps!
