It basically means that if your software just uses the library as a
library then it is NOT a derivative work, i.e. a work derived from the
original, and as such will not need to abide by the license conditions
concerning derivitive works.  A derivitive work uses, or has at some
point used and since evolved, actual source code from the library
itself.
