Actually, if you're not linking with the code, I think you just have to provide the license along with your software. I'm not positive, tho, so definitely read the license.
phidauex is absolutely correct - it's extremely readable legalese.
I ran into this issue when I was considering using some code from GNUStep ( wanted to subclass their version of NSBrowser, but I wound up writing my own from-scratch version). I posted the question to their mailing list and got a few helpful replies.
Why don't you try asking the author or support group of the software you're including?
