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:
