Dear Tim, many thanks for the update and your patience!
This is a very common error when you don't run install scripts. If it isn't mentioned in the manual, then it should be, if it is in the manual, then you should have a read through that. [1]
I am very new to CRUX, but yes, in hindsight, I remembered reading about the pre-/post-installation in the handbook. My mistake was that I did not enable the `runscripts` option in prt-get.conf as it is in fact recommended in the handbook (I postponed "tweaking" my configuration for some time). On the other hand, being a CRUX newbie and just looking at the error, it was not obvious to me that this results from not having run various pre/post-installation scripts in the docbook dependencies. Anyhow, now I have learned something again and also understand why allowing those scripts as default is not always advisable. So far, CRUX is really awesome and I am wondering more and more why package (and system) management I have experienced in other distributions had to be so complicated/opaque/unsatisfactory. Best regards, Martin
