What is wrong?

Version: 2.5.2
Python-3.9
FreeBSD 14.0

Start with tests/cli/init.py and tests/cli/test_compress_decompress.py, then reproduce collection with the missing laspy.cli.core dependency on the reported Python and FreeBSD versions. Done means missing CLI dependencies are handled during collection without an INTERNALERROR, with the expected skip result.
