yay!! thats it!!  i knew it was going to be something like that, but i just
couldnt place my finger on it.  the guy i built this box for, previously had a
linux box running that got exploited.  their exploit was running stuff from
within the /tmp directory (i believe they exploited the out-of-version phpbb
that was running).  anyway, long story short, the gent i built this box for has
prewired himself with a fear of the /tmp directory (with good reason, i
suppose).

once i remounted without noexec, it worked as expected.  good call, philip!
