New comment by ericonr on void-packages repository https://github.com/void-linux/void-packages/pull/22932#issuecomment-819067928 Comment: https://github.com/benfred/remoteprocess/blob/master/build.rs <-- it forces static linkage for libunwind on musl, which is probably what's pulling in the requirement for libz. Should be fixable by asking upstream to offer at least an env var for it.
