Here's the problem (according to Claude):
What broke: ptxdist cargosync downloads each crate from Cargo.lock into SRCDIR while generating iceoryx2.cargo.make. In ptxdist 2026.06.0, upstream commit ee282ffe7 ("setup: add mirror for crates.io", May 2026) changed the URL that cargosync uses for each crate from a real URL (https://crates.io/api/v1/crates/<name>/<version>/download) to the make expression $(call ptx/mirror, CRATESIO, <name>/<version>/download).
Why that fails: that expression is only meaningful when make evaluates it — which happens later, in the normal get stage, when the generated .cargo.make is parsed. But cargosync itself runs as a shell script (ptxd_make_world_cargo_sync_package in scripts/lib/ptxd_make_world_cargo.sh) and passes the string unexpanded to ptxd_make_get, which only understands real URL schemes (http://, git://, …). It splits the string on spaces, sees $(call as the "URL", and dies with exactly your error — Unknown URL Type! URL: $(call.
The download is only attempted when the .crate file is missing from SRCDIR (if [ ! -e "${path}" ]), so upstream's own websocat.cargo.make etc. were regenerated on machines that already had all crates cached — that's presumably why the regression went unnoticed. I checked upstream git: there's no fix yet

I hope it helps!
