Description
There appears to be an issue loading libjpeg.8.dylib from binaries and libraries on 10.4.11/PowerPC.
$ /opt/local/bin/jpegtran
dyld: Library not loaded: /opt/local/lib/libjpeg.8.dylib
Referenced from: /opt/local/bin/jpegtran
Reason: no suitable image found. Did find:
/opt/local/lib/libjpeg.8.dylib: incompatible cpu-subtype

The machine is a 700MHz G3. It looks like the dylib was built for G4.
$ lipo -info /opt/local/lib/libjpeg.8.dylib Non-fat file: /opt/local/lib/libjpeg.8.dylib is architecture: ppc7400 $ osascript -e 'system attribute "cput"' 264 $ osascript -e 'system attribute "cpuf"' 264

a lot of software will assume a 7400 as a minimum these days, as that is what Rosetta supported.. Very few are trying builds with G3's any more, so you might expect troubles.
The assembler is usually set to build for all ppc subtypes. I have tweaked many things for G4 and G5, like redoing the assembly in OpenBlas, but I'm not running MP on any of my G3s, so it's largely uncharted territory.

Building libjpeg-turbo 2.1.0 from source, it looks like ppc7400 is built whenever WITH_SIMD=ON. So it looks like a bug in the library - but I think we can work around it by configuring with -DWITH_SIMD=0 on G3 in the Portfile.

good luck sorting that out! There are some Portfiles that query compiler features using sysconf...grep the repo for examples.

And what is the CPU subtype of /opt/local/lib/libjpeg.8.dylib and what is the specific model of processor that you have in your computer? Try running:
Note that /opt/local/lib/libjpeg.8.dylib is provided by the libjpeg-turbo port, not the jpeg port. (The jpeg port provides /opt/local/lib/libjpeg.9.dylib.)
It is possible that libjpeg-turbo is adding
-archflags for a specific newer PowerPC processor than the one you have; if so, we should fix that.
