new CR2 and old dcraw

Older versions of dcraw don't handle new cr2 files at all (the output is just a checkered mess). I'm not sure exactly what the first version that works is, I've only verified on 9.27 and 9.28, but I know 9.19 does not work.

So, on windows - no problem - dcraw is included in the IM package. And I've got everything working there. But on linux (particularly Oracle Linux 7, which is redhat), it's not included and the version available in the standard repository is only 9.19 (the IM version is 6.7.8.9).

There is no ufraw package available. How can I get imagemagick to work - it wants ufraw? Or get an updated dcraw package?

I realize this is more of a linux question than an imagemagick question, but I'm hoping someone can point me in the right direction.

Dave Coffin's page used to be at http://cybercom.net/~dcoffin/dcraw/ but that currently seems broken. It seems to have moved to https://www.dechifro.org/ . Source for dcraw is at https://www.dechifro.org/dcraw/dcraw.c . If you have a C compiler, building dcraw is simple.
