Hello! Our current version of librsvg is officially unmaintained, and the latest version requires Rust.
I've succeeded in making the latest version build, but there are a couple of problems. * Module dependency cycle: <https://bugs.gnu.org/31392>. * librsvg requires Cairo 1.15, which is not a "stable" release branch. * It bundles 59 Rust libraries. Here are the Rust libs: aho-corasick/ bitflags/ bitflags-0.9.1/ cairo-rs/ cairo-sys-rs/ cssparser/ cssparser-macros/ c_vec/ downcast-rs/ dtoa/ dtoa-short/ either/ float-cmp/ fuchsia-zircon/ fuchsia-zircon-sys/ glib/ glib-sys/ gobject-sys/ itertools/ itoa/ lazy_static/ libc/ matches/ memchr/ num-traits/ pango/ pangocairo/ pangocairo-sys/ pango-sys/ phf/ phf_codegen/ phf_generator/ phf_shared/ pkg-config/ procedural-masquerade/ proc-macro2/ quote/ quote-0.3.15/ rand/ rand-0.3.22/ regex/ regex-syntax/ siphasher/ smallvec/ syn/ syn-0.11.11/ synom/ thread_local/ ucd-util/ unicode-xid/ unicode-xid-0.0.4/ unreachable/ utf8-ranges/ void/ winapi/ winapi-0.2.8/ winapi-i686-pc-windows-gnu/ winapi-x86_64-pc-windows-gnu/ Have anyone packaged any of these? Or made a Rust importer? Here is a package definition for librsvg (use with guix package -f).

Feedback welcome. I'd like to get this into the next 'staging' cycle and will attempt to package some of the Rust libs separately. Propagating this Cairo variant is unfortunate however, perhaps we should make it a regular input for now?
