Hi Urs, List,

b) Linux, self-compiled

I've never experienced this issue with self-compiled LilyPonds. I assume this is *not* because self-compiled versions implicitly use the bundled libs but because they implicitly compile against what is available in the system. But if that assumption is correct I'd experience the same issue if I should run a self-compiled Lilypond that has been compiled some time ago, e.g. before a major Linux upgrade.

This was my previous method, building from most recent source (which oddly also reported itself as a version more recent [ie, higher version number] than that listed on the website as the latest source).

This is not odd.
At a certain point Lily is released and gets the next version number. This is what you can download as a release or as the source code.
The version is increased in the Git repository, and development happens on release+1 until that is released and made public.

However, I am no longer able to get a working Lilypond via this method, because Gentoo Linux has dropped support for Guile-1.*. Does newer Lily work with Guile-2.*, or would this still be an issue?

Yes, this is still an issue. People have successfully built LilyPond against Guile 2, but that seems to still require patches and doesn't work in a satisfactory way (e.g. *significant* performance issues).

I'm also unfortunately not able to help in the more generic issue of ghostscript, because I was updating Lily fairly regularly and can't check your alternative case. However, for the brief window when 1) I still had Guile-1.* on my system and 2) had a version of ghostscript that differed from that packaged with Lily, this was the issue I would encounter. I wrote the list a couple times over this issue, I think back in November or so.

Yes, I think this basically is the issue I'm trying to solve with my Frescobaldi patch.

Hope that helps (though, let's be realistic here: I'm not very helpful, alas!),
