>Description:
	This was an odd thing to track down.  For sake of brevity, I won't go into
discussion of how this all came to be, just what I've observed.  What was originally
(seemingly) an amavisd-new problem, turned into a spamassassin problem, then into
a perl problem, but now it seems the problem is in patch-freebsd.sh.

	Regardless of WITH_THREADS=yes or WITH_THREADS=no, it still links in pthreads.
Also WITH_THREADS=no, the port still builds a threaded perl.  However, with neither
specified, it still seems to link in libpthreads.  This leads to a Bus Error, given
a sufficiently large parameter to 'eval'.  To keep things from being repeated, and
to save my poor fingers, this bus error is documented here:

http://rt.perl.org/rt3/Ticket/Display.html?id=36667
(requires a username and password which can be obtained at http://rt.perl.org/perlbug/)

>How-To-Repeat:
	How to repeat getting the Bus Error, see the link above.  Since thats to repeat
the bus error, and not the problem stated above, to repeat is to just install the port.

>Fix:

	Remove these lines from /usr/ports/lang/perl5.8.7/files/patch-freebsd.sh

	Or remove files/patch-freebsd.sh (seems to work just fine w/o it, though have not
tested it with the WITH_THREADS= option).
