Comment: sudo isn't necessary to build source packages... fakeroot will do.

Old notes
Check if the package has a debugging version available. In general, debugging packages will be named with a -dbg suffix
- If not, you can generally* build one this way:
- Something to keep in mind: if you would like to create a build you're going to need to have the relevant deb-src lines in your /etc/apt/sources.list
Install the development scripts:
sudo apt-get install devscripts
Install the build-time dependencies for the package:
sudo apt-get build-dep <package>
Build .debs for debugging:
export DEB_BUILD_OPTIONS="debug nostrip noopt" fakeroot apt-get source -b <package>
Install the needed .debs (they will be in the current working directory if the build succeeded):
sudo debi <package>*.changes
* most of the packages support the build of debugging version in this way. If that doesn't work for a package you can open a bug against it.
