Rust Modules via Git Commit and gsettings schema

I'm trying to package the newsflash RSS reader 
(https://gitlab.com/news-flash/news_flash_gtk) and running into two issues:
1. The dependency of the clapper video player, while only needed for its 
libraries, is failing when I attempt to invoke the player itself with:
---
(clapper:2462): GLib-GIO-ERROR **: 18:37:09.320: Settings schema 
'com.github.rafostar.Clapper' is not installed
fish: Job 1, 'clapper' terminated by signal SIGABRT (Abort)
---
The libraries work, but I feel like I should make the player work as 
well even if I'll never use it.

2. Newsflash itself has a dependency on a crate html2gtk defined in its 
cargo file as:
---
[dependencies.html2gtk]
features = ["ratex", "video-thumbnails"]
git = "https://gitlab.com/news-flash/html2gtk.git";
--
This crate without any speciifed version breaks both url2pkg with
--
fetch: Unable to fetch expected file html2gtk-0.1.0.crate
*** Error code 1

Stop.
make: stopped making "distinfo" in /usr/pkgsrc/wip/test
Traceback (most recent call last):

and the structure of cargo-depends.mk doesn't have an obvious solution I 
can see for this.

lang/rust/cargo.mk seems to list this as a TODO thing?
---
# TODO: some Cargo.lock files include git+https sources which need to be 
fetched from the URL (not necessarily resolving to a crate.io url)
DISTFILES?=                     ${DEFAULT_DISTFILES}
---

(Newsflash also has an optional feature, libc, I need to remove to build 
it on NetBSD from testing outside pkgsrc, but I can work on this after I 
get it to start building in PKGSRC at all).

I've pushed these broken build files to wip as clapper and newsflash 
respectively for examination.

Thanks,
Gourd
