RFC 2136 Updates failing {solved}

[pahrohfit]

Since early December, I've not had a successful RFC 2136 update.  After looking around, and trying to nsupdate by hand, I got back an error message stating /lib/libreadline.so.6 was missing.  Nothing shows any fault in system.log.

nsupdate -k dns.key -v dns.cmd

Shared object "libreadline.so.6" not found, required by "nsupdate"

Creating a symlink to libreadline.so.8 corrected the issue, so it looks like nsupdate needs a recompile?

ln -s /lib/libreadline.so.8 /lib/libreadline.so.6

nsupdate -k /tmp/dns.private -v dns.cmd

Outgoing update query:

pfSense 2.2, around Dec 6 -> today, all have the same fault.  amd64 is the only thing I've tested.

thanks. Go figure the one system where I had a slew of test nsupdate things setup just happened to be 32 bit when most all my test/dev systems are 64.
