[Pkg-rust-maintainers] trouble building rust 1.34.2

[Enrico Weigelt, metux IT consult]

Hi folks,


I'm trying to build rust-1.34.2 on stretch (need more recent version
to build latest thunderbird), but getting a strange failure:

error: no matching version `^0.1.1` found for package `rayon` (required
by `rustc_data_structures`)
location searched: registry `https://github.com/rust-lang/crates.io-index`
versions found: 1.0.1
Traceback (most recent call last):
  File "./x.py", line 11, in <module>

debian/rules:200: recipe for target 'override_dh_auto_build-arch' failed


I've checked for the missing rayon version, but this doesn't seem to
exist at all - not even on upstream's github repo.

Does anyone have an idea what's wrong here ?
