Task 84's log got further than any run so far — 4 of 8 packages (aardvark-dns, passt, fuse-overlayfs, unraid-podman) built successfully — and surfaced four distinct, genuine build-time issues for the rest: 1. podman: go.mod parsing failed with "invalid go version '1.25.6': must match format 1.23". Root cause: slackpkg's batch-mode `install gcc` (verified directly) pulls in every gcc-<lang> sibling package Slackware's gcc SlackBuild produces — including gcc-go, an ancient bundled go1.16.5. Our Go bootstrap only installed the pinned $GO_VERSION when `command -v go` found nothing, so gcc-go's go1.16.5 silently won. Fixed by always installing/overwriting the pinned Go and prepending it to PATH, regardless of what else provides `go`. 2. crun: "no suitable Python interpreter found" — added python3. 3. netavark: build.rs (via prost-build) needs a `protoc` binary; Slackware packages no protobuf/protoc at all. Added the official prebuilt release binary, pinned + checksummed (no `unzip` on this image either, so extracted with `python3 -m zipfile` instead of adding yet another package). 4. conmon: `make install`'s docs target needs go-md2man, not packaged by Slackware and no prebuilt release exists upstream. `go install` it, pinned to a tagged release, now that our own Go is reliably on PATH. All four verified directly against vbatts/slackware:15.0 on the actual runner host before this commit. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
