Prepare build environment
Add unstable repo to /etc/apt/sources.list

To build packages into a new repo (du3) we need to use old build environment based on du2, but new packages should come from the new repo, that is why we placed du3 above du2 in the list.
deb-src lines instruct apt where it should get upstream source packages. In our example it is buster (a codebase of debian).
update existing packages:
apt-get update
Perhaps you will see key errors due to update stage something like this:

Install build packages:
install packages:
du3p03% apt-get install gmake build-essential
If you want to build some package from an existing repo you need to install git to clone the repo:
install git
du3p01% sudo apt-get install git
Now clone a repo (du3), at this stage you have created an account at bitbucket and ask to provide you access by info: http://www.dilos.org/conact-me
clone repo:
du3p03% git clone https://bitbucket.org/dilos/du3.git
go to components directory:
cd du3/components
you are ready to build your package from userland, for example: apt
cd <du3>/components/p0f gmake JOBS=4 deb (JOBS is the number of parallel build processes you want to use)
After the building process is done, you find the built package(s) in <du3>/components/${component}/build directory
How to port a new package
Choose a package you want to port. For example, apache2. Go to the debian packages page at https://packages.debian.org/buster-backports/apache2 and copy the correct name of the source package in the right column ("Download Source Package apache2:"). Remember (or copy) "apache2". Install additional packages to manipulate the source code:

Now we can port the package. First of all you should install (possible) all dependencies to build the package. At this stage the build system does now know anything about dependencies, install them manually:

install jdupes dependencies
create package directory and copy Makefile from another package
update Makefile with build flags (CONFIGURE_OPTIONS)
build package by:
gmake JOBS=4 install
Create directory 'debs' with structure of files for DEB package build by dpkg-buildpackage.
For example take a look another components
build package(s):
gmake JOBS=4 deb
if you want build packages in your component root directory you can add flag WS_DEBS:
example:
gmake JOBS=4 WS_DEBS=`pwd` deb
as result you can find package at your component directory and be able to install it by 'dpkg -i <your package.deb>'
For more information about environment variables or build flags you can take a look <du2>/make-rules/deb_src.mk
