Generally what you would do is create a slave port of the dependency
with the options settings you require. Doing this to turn off the DOCS
option would be unprecedented though.
I believe the consensus nowadays is that DOCS should control installing
documentation that takes little or no effort to generate. If you need
to install a huge dependency tree in order to generate documentation,
then that should be controlled using a different option. Whether to
have that option default to either ON or OFF is at the discretion of the
So my advice here is open a PR to get devel/ragel modified, and in the
mean time try and ignore all those unwanted dependencies while you work
on your own port.
