license question with non-GPL library

[Scott]

Hi,

I am attempting to ascertain my obligations with regards to a software
project I am writing.  This project is to be licensed under the GPL, but
it links to a non-GPL library.  This library is licensed under the 'new'
BSD license, so it is compatible with the GPL.  However, my question is: do
I need to distribute it's source-code with my application (i.e. is my
application considered a 'derivative' work?)

Thanks,
Scott
