OK. I'll try my best to answer this :-)
First of all, I _never_ use `apt-get -b source <pkg_name>`. I am happy
using the pre-built binary packages. I only re-compile Debian packages
when I need to change some build-time configuration options. These are
the steps I follow:
1. `apt-get source <pkg_name>` in an empty directory.
2. Move into the package's build directory.
3. Change the build version (`dch` + editing debian/changelog, I
usually add 'mt' rather than bump the build version).
4. Make any changes I want to the build steps and the source itself.
5. Use `debuild` to build both binary and source packages (they end up
in '..', i.e. in the download directory).
I hope it now is clear what I mean with "build the source packages".
Since I've bumped the build version I keep the original source packages
as well. After this you can delete the directory with the sources since
you can recreate it using the source package.
AFAIK a Debian source package consists of three files, .dsc, .tar, and
.diff. You can use `dpkg-source -x <pkg>.dsc` to unpack them. You can
use `dpkg-buildpackage` to build the binary and source packages.
I hope that clears up what you read.
`apt-get build-dep` will download and install all packages that a
specific source package has as its build-dependencies. E.g. on my system
`apt-get build-dep` installed libncursesw5-dev.
