I think VueScan is proprietary software. If it can use external copy of dcraw, that should work.
dcraw itself should build:
https://ports.macports.org/port/dcraw/details
ufraw on top of it may be promising:
https://ports.macports.org/port/ufraw/details
Not sure if builds, can check tomorrow. Ping me here.
If it is broken, I can try to fix. Given dependencies, it should work.
Re Macports: if users of software don’t report that something is broken, chances are slim it randomly gets fixed, especially for PPC. We have like 2–3 people with hardware to test and maybe 2 more with willingness to work on PPC, given someone tests it on hardware.
Those 2–3 people have priorities for ports and macOS versions. Say, I do not normally test stuff on 10.5, unless I have a specific reason to, and almost never on 10.4 (I won’t work on fixing something for Tiger beyond trivialities either: sorry, it is just too badly broken). My ports must build on 10.6 ppc however, and every ppc-related fix should work on 10.6. Usually that implies support for 10.5, but I can’t guarantee that.
Then, there is just no time to thoroughly test every random port or sometimes test at all, because there are no tests, or they are broken beyond feasible repair. So, say, if you want to have a functional RAW converter with support of recent cameras on PPC via Macports, this will probably require your active participation in the process by testing in your environment and for your use cases. Having such feedback will improve results for you and save developers’ time.
For instance, I have recently fixed `rawstudio` build, but it was not working on my system. If, say, it gonna fail identically on your system, we can try fixing that (as I recall, there was a missing symbol on launch; that should be fixable).
Or try `libopenraw-legacy`. Or try `dcraw` with `ufraw` and let us know what fails.
We just don’t have a facility of someone leading the thing from fixes to the build all through to production-quality solution. Help us to help you
