Thanks for your response.

Since originally writing that message, I had done some tests (there was a
misconfiguration in mailer that my browser called on the system I was
sending from so the message got sent out much later when it was corrected).

I had tried running the exact same executable both in the jail and 
outside and
got a different set of libraries.  One odd thing that I had also noticed 
is that when I
ran "ldd" against the same executable, I came up with a different set of 
I'm not sure what controls the library searches.  As far as I can tell 
the libraries
are the same also.

However, since then, my /var/run/ld-elf* files have changed.  I no 
longer see
the problem or the differences in ldd.  This may have corrected the problem.
