If you decide to do a PPC-compatible build then you'll need an older system and use "-arch i386 -arch ppc" in the compiler options.

Thank you for your help Michael.  Unfortunately, I still can't get it to build all the way.

I did as you said for building libusb and installed --

matt$ file /usr/local/lib/libusb-1.0.a 
/usr/local/lib/libusb-1.0.a: Mach-O universal binary with 2 architectures: [x86_64:current ar archive random library] [arm64:current ar archive random library]
/usr/local/lib/libusb-1.0.a (for architecture x86_64):	current ar archive random library
/usr/local/lib/libusb-1.0.a (for architecture arm64):	current ar archive random library
matt$ lipo -archs /usr/local/lib/libusb-1.0.a 
x86_64 arm64

Then I went to build gutenprint 5.3.5-pre1 fat(x86_64 and arm64), and it errored out building the backend.  Interestingly, if I switch the architecture around (arm64 and x86_64), it will fail with the same error but show capture_entitlements in libusb-1.0a[arm64].......   I went back and built and installed libusb for only arm64.  Same errors when I go to build gutennprint backend.

Thank you for your offer.  I think most of it would be over my head and lost on me.  I'll play around with libusb and gutenprint a bit more.  If nothing else, I can at least test the v5.3.5-pre1 release and update the build script and uninstaller.

Matt
