[Mimedefang] MIMEDefang vs. NetBSD 1.6.1

[John Nemeth]

     I've been trying to MIMEDefang to run on NetBSD.  I've tried a
couple of different versions of the OS.  With the latest release
version (1.6.1), I can compile MIMEDefang, but when I try to use it,
the slave crashes when sendmail connects to it.  I also tried it on a
-current system (development code) and it worked there.  The primary
difference between the two systems is that the 1.6.1 machine is using
GNU pth 2.0.0 and the -current system is using a native pthread library
(the released system doesn't have a native pthread library).  Is there
a preferred pthread library to use when an OS doesn't have a native
one?  My setup on the 1.6.1 box looks like:

MIMEDefang version 2.34

I'm using the Roaring Penguin version of MIME::Tools.  Also, I'm using
Sendmail 8.12.9.  Is there any other information that's needed?
