Yes, but if its inability to properly grok --option="" is the only reason we want to add a dependency, wouldn't it suffice to simply state in the documentation (1) how to recognise the symptom to see if the version the user has is too old, e.g. "if you see this error message", "run 'perl -v' to see if your perl is older than X", etc. and (2) how to work it around, i.e. "instead of giving an empty value with --option='', say --option ''"?
