Hello Guix, I would like to update the CLOG [1] package in Guix to version 2.3. Clog is a Common Lisp package and has several ASDF systems, clog, clog/docs and clog/tools. I packaged the dependencies of CLOG and the clog and clog/docs ASDF systems. But now I'm stuck with clog/tools ASDF system. When building it, the build system tries to compile a file from a dependency (clog-ace, which I added to the inputs), but fails to write a FASL file in the store. I don't understand why that is happening and I'm not a Common Lisp expert. I tried multiple things, like commenting out some ASDF systems, deleting files, etc, but no luck so far. Can some Common Lisp expert help me with this, please? I attached the build log, and the patches I have so far. Thanks, Roman. [1] https://github.com/rabbibotton/clog
