• -s|--syncdeps install build time/run time dependencies
• -c|--clean keep repositories, but cleanup after the build otherwise
• -f|--force build the package, even if there already is one

Normally makepkg -sc is sufficient; if a rebuild is necessary use makepkg -scf, if the build needs debugging lose the -c makepkg -s.

`makedeb` is not completly compatible with makepkgs pkgbuild format. If you want to build a debian-package and have checked out this repo on a debian system with makedeb installed, there is for (most) packages a patch file present, you can apply with patch < makedeb.patch, after that just use makedeb as you would makepkg.
