gnomefreak@FeistyFawn:~/ff_build/firefox$ dh_make -e gnomefreak@gmail.com -f ../firefox-2.0.0.1.tar.gz
The directory name must be <package>-<version> for dh_make to work!
I cannot understand the directory name or you have an invalid directory name!
Your current directory is /home/gnomefreak/ff_build/firefox, perhaps you could try going to
directory where the sources are?
Please note that this change is necessary ONLY during the initial
Debianization with dh_make. When building the package, dpkg-source
will gracefully handle almost any upstream tarball.
