Hmm. I think the best thing is to create a new script in SAGE_ROOT/local/bin/ and encapsulate the check in there. Then in your script call that. I.e., make something that does what you thought newest_version did. First find what the relevant commands are in say apt, rpm, etc., as inspiration for a command name. Regarding the implementation of that script, you could maybe check for ls returning an error (or whatever) as above. However, better would be to write something in Python, e.g., #!/usr/bin/env python import os # do something with os.listdir() --- By factoring out this functionality in a script, we avoid awkward buggy so called "best practices" appearing in spkg-install scripts. As much as possible, anything that could possibly be replicated in several spkg-install scripts should be factored out.
