If you installed via Synaptic you likely just installed the binary (i.e. pre-built) packages, which include the header files (necessary for building your own, custom blocks), libraries, and the applications/examples that come with GNURadio. If you want to modify the existing examples, you'll need to download the source (some instructions are at: http://gnuradio.org/trac/wiki/UbuntuInstall#InstallingGNURadio - including using svn or git) - at least for the C++ examples, the python scripts are easy to modify. If you want to create your own custom blocks outside of the gnuradio source tree, you can just take a look at the gr-howto-write-a-block code (the original documentation is at http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html) - it exists inside the GNURadio repository. For help on using Git, take a look at: http://gnuradio.org/trac/wiki/DevelopingWithGit
