Did not know this forum existed before, so here it is.
The implementation in darktable is pretty much the same as in ml's deflick.mo (http://www.magiclantern.fm/forum/index.php?topic=10496.0) module.
You will need
darktable 2.0 or newer. (2.0.4 is highly recommended)
Video explanation on how to use it:

Textual explanation:
- Start darktable
- Import images
- Open one image in darkroom
- Edit it to your liking
- In exposure module in the right sidebar:
- set mode to automatic
- set the two very same parameters: percentile and target. they have exactly the same meaning as in deflick.mo
- Switch to lighttable
- Copy history stack of the image you edited
- Select all the images
- Paste history stack to the selected images
- Export images. That is all.
Exported images will have pretty similar exposure.
Now you can do whatever you want with them - e.g. assemble them into a video.
IMPORTANT: only available for raw (not even SRAW!) files, i.e. .CR2, .NEF, etc; NOT FOR ANYTHING ELSE (ldr/hdr - jpg, tiff, png, etc)
