New review comment by ahesford on void-packages repository https://github.com/void-linux/void-packages/pull/39416#discussion_r980125414 Comment: ```suggestion TMPDIR="${PWD}/build" python3 -m pip wheel --no-deps --use-pep517 --no-clean \ ``` A full path seems to fix the rust build. Because I can't recall why I chose `$TMPDIR`, but `$TMPDIR` is the variable [identified by POSIX](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08_03), we should prefer this over `$TMP`. Still, the change to an absolute path should be tested on at least a few other `python3-pep517` packages.
