Hah! RSS-aggregator Liferea could use multilple html-engines. Old versions - gtkhtml, recent versions - webkit. I want build with gtkhtml. How to create package definition for old version Liferea with gtkhtml? The problem is that Guix does not know anything about this library, right? Well, I build gtkhtml locally, what next?
This is another white spot in the manual! For example, I need to build packages with cross dependencies, and? In this case the dependencies are consistent, but there is still no clarity on how to act..
