I've committed a change for this now. I've also posted a blog entry  
about it at http://www.nagioscommunity.org/2007/03/25/installing-the-

nagiosplugins.org too later.

Hopefully, the blog entry explains all the necessary bits. Let me  
know if I've missed anything or it doesn't work as expected.

I'll cut a 1.4.7 release on Tuesday if there's no adverse reactions.
