I've been using Mageia 5 since some days (first-time-user) and have a long-time experience with Mandrake/Mandriva (nearly from the beginning). I created a lot of packages for my own need and did some contributions with RPM Spec files and also bug fixes to these.
I've searched in vain for any hint about a Photivo package, so decided to create my own one.
from http://photivo.org/
Photivo is a free and open source (GPL3) photo processor. It handles your RAW files as well as your bitmap files (TIFF, JPEG, BMP, PNG and many more) in a non-destructive 16 bit processing pipe with gimp workflow integration and batch mode.
Photivo tries to provide the best algorithms available; even if this implies some redundancy. So, to my knowledge, it offers the most flexible and powerful denoise, sharpen and local contrast (fake HDR) algorithms in the open source world. (If not, let's port them ) Although, to get the desired results, there may be a quite steep learning curve .
I will create a SPEC file (and test it of course ) and would open a request for a new package.
Unfortunately I cannot maintain it myself as my free time - apart from taking / processing photos - is devoted to music and the free music score editor Canorus (this one already has a maintainer here, though the latest RC is not used, so I will make a contribution here too if you like).

Edit: Some useful links I found today:
https://bugs.mageia.org/show_bug.cgi?id=4731 (it looks like a dependency issue, though I it could be dated)
http://www.cyron.cz/rpm/mageia/4/x86_64/ - apparently there is already an archive for M4... (but not source of the package, hello Cyron ?)
