For build dependencies, building with pbuilder (or one of its variants)
helps a lot for finding build dependencies, since anything that isn't
declared is going to be missing, and thus cause an error. (Unless the
dependency is conditional.)
For most things with a good test suite, the run-time dependencies are a
subset of the build dependencies. That's not always completely true, but
it still helps.
For figuring out the runtime dependencies, using a chroot or a virtual
machine (kvm, virtualbox) helps: set up a base install, then install
your package into that and excercise it to see if anything is missing.
In the end, you will need to read upstream documentation (if any) and
browse the code to find out special cases.
