Yes, that was me... :-)

I thought we could just edit unprocessed elements in in *.adoc, but as
I looked at them, some seemed really simple to be added to docbookrx in
order to avoid manual work.

It is just a shortcut to avoid pkg-config and tell it the paths
manually. I assume the result would be the same if pkg-config worked.

This is not that different from compiling software outside of MacPorts,
but linking to MacPorts libraries. This can break with updates to ports,
but it will work as long as the name of the .dylib does not change and
the ABI is compatible. If any of this changes, ports linking to the
library would also break.

Indeed, the external libraries caused the problems for me. That's what I
get for trying to save time by not compiling the libraries again...
