With those fixed dependencies, I realise docbook-utils under scallywag 
will pull in a lot of texlive collections, so I'll remove some 
collections locally to check dependencies on underlying packages, rerun 
zp_texlive_prep and zp_texlive_finish to ensure those still work, and 
retry the build.

Specifiying explicit dependencies could possibly avoid this situation, 
or at least provide pointers to the source of issues, in the future, if 
texlive packaging and dependencies change again, improve robustness of 
the build, provide documentation of that, and "for avoidance of doubt".

For example, as well as the component dependencies mentioned earlier, 
docbook-utils cygport explicitly requires grep, perl, sed, despite those 
currently being cygport dependencies, not mentioned in the docbook-utils 
docs, and a perl module being required; all but perl are also currently 
Base packages; similarly cygport explicitly requires those and other 
Base packages, many script packages explicitly require bash, and other 
packages explicitly require cygwin, although they are Base and essential 
to everything.
