Thanks a lot Jaret,

Finally, there is an experience programmer who is willing to spare the
time to develop eudev package for Devuan (actually for Debian, but I
prefer to refer to Devuan instead). I really appreciate this.

However, it is still no go for me. Perhaps I took harder route so there
could be some dependencies that have not been met which make the build
package fails at very early stage.

The followings are what I have done so far.

1. I am using the minimal install of Debian wheezy with 
linux-image-3.2.0-4-amd64
    All packages required by eudev are from Debian wheezy, except the 
ones below
2. Install libcryptsetup4 and libcryptsetup-dev from Debian wheezy-backports
    The version of libcryptsetup-dev on Debian wheezy is 2:1.4.3-4 but 
eudev requires libcryptsetup-dev (>= 2:1.6.0)
3. Get kmod 18-3 source package from Debian jessie, re-compile and 
install it on Debian wheezy
    The version of libkmod-dev on Debian wheezy is 9-3 but eudev 
requires libkmod-dev (>= 15)
4. Install linux-image-3.16.0-0.bpo.4-amd64 
linux-headers-3.16.0-0.bpo.4-amd64 from Debian wheezy-backports
    This also pulled some necessary packages and upgrade initramfs-tools
5. Reboot to use linux-image-3.16.0-0.bpo.4-amd64
6. Build eudev package and what I got is shown below

It looks like that I missed some required packages, but I have no clue
what would that be. Could you please let me know which package should I add?

Or do you think I did something wrong? If so, could you please let me
know which part would that be?

Thanks a lot in advance.

Cheers,

Anto
