I didn't think EPD offered dev versions of packages. I can only see 0.8.2. In any case, it depends on how recently the dev version was updated. The RANSAC code was only merged into master about 2 months ago. (Any pulls from master in the last 4 months will be labeled 0.9dev.)

 
Yeah, sorry for that. Must have pulled master in at sometime for some interesting feature. I am still regularly confused by the fact that enpkg --remove does leave the egg in site-packages, and for some reason I don't have the git folder of skimage anymore, so I thought it must have come via enpkg.
