I have a suspicion that this is due to not having 'gettext' package installed. If this is the case, will close this issue and report bug against gettext_macros crate for the unclear error message.

[khimaros]

Closing. See Plume-org/gettext-macros#7

I was able to resolve the gettext failure, as mentioned above.

However, I'm now bumping into rust-lang/rust#58922 while installing the sqlite crate:

+ cargo install --no-default-features --features sqlite

Is there a version of rustc/cargo which is known to work?

[trinity-1686a]

there is a compiler release tagged in ./rust-toolchain, it should have been used by cargo instead of your default one, I don't know why it did not

[khimaros]

It looks like this was due to bad precedence in $PATH -- the rustup toolchain bin dir was in the $PATH explicitly and came before the cargo bin dir.
