As Peter said it has to do with being a derivative work -- if you
dynamically link against a library that falls under GPL and you
release your application, then you must also release your source code
under GPL. Yes, it is transitive. No, simply distributing a package
licensed under GPL with your package does not exhibit this problem,
there needs to be a functional API dependency which is typically
expressed by static or dynamic linking or code inclusion. LGPL
resolves this by allowing dynamic linking. As a non-lawyer I approach
this by considering it safe to have LGPL in the dependency chain but
never GPL, unless the entire chain is already GPL.

Thank you Kon. The denizens of #chicken appreciate it. (Feel free to
join us sometime.)
