libpixman: Opportunistic use of libraries when building demos

[dbl001 (dbl)]

I'm running MacOS Sonoma 14.4.1 on an INTEL iMac 27". For some reason the -arch is arm64.

Replying to dbl001:

Because you have requested the +universal variant, which means build for multiple architectures. On Sonoma, it means x86_64 and arm64, and in this port it happens to build them separately.

And apparently the +universal variant doesn't work right in this port anymore.

If you don't have a desire to build arm64 on your Intel Mac, don't use the +universal variant.

Actually, what's weird here is that libpixman is complaining about the wrong architecture in libraries belonging to ports that are not dependencies of libpixman: atk, cairo, gdk-pixbuf2, glib2, gtk3, harfbuzz, pango—ports that can't be dependencies of libpixman since libpixman is a dependency of cairo already. libpixman shouldn't be using those. It looks like this is happening when libpixman is building its demos. So the port should be changed not to build the demos.
