>Description:
	i was playing around with the gnupg package (because pgp2 and
	pgp5 both didn't seem to do what I wanted wrt compatibility
	with various key formats, etc) and noticed that by default
	IDEA support isn't provided in gnupg (because it's patented)

	there is a known workaround listed on the gnupg web site:
		http://www.gnupg.org/faq.html#q3.3


>How-To-Repeat:
	try to read a message encrypted using IDEA (pgp2 messages?),
	and watch gpg fail with:
		gpg: protection algorithm 1 is not supported

>Fix:
	in short, grab
		ftp://ftp.gnupg.org/pub/gcrypt/contrib/idea.c
	compile it up with:
		gcc -Wall -O2 -shared -fPIC -o idea idea.c
	install as
		/usr/pkg/lib/gnupg/idea
	add to ~/.gnupg/options:
		load-extension idea

	btw: i'm not asking for this to be done by default in the
	gnupg package. however, having it done if mk.conf
	USE_IDEA==yes would be convenient.
