AFAIK the following message from build log indicates incorrect regular expressions in docbook-utils:
> grep: character class syntax is [[:space:]], not [:space:]

The character class must be inside bracketed expression, thus double brackets, please see man grep. The new grep-2.7 checks for this common fault:
