check scripts need to be explicitly included in EXTRA_DIST. this is one of the classic Automake gotchas. check_SCRIPTS tells Automake: “these are test-related scripts that should be built/copied into the test environment.” But check_SCRIPTS does not imply distribution. Only *_SOURCES, EXTRA_DIST, and a few others (like dist_*) imply files are part of the distribution tarball."
