cargo @0.14.0: build error

[mathomp4 (Matthew Thompson)]

When I tried to build cargo (actually ripgrep), I got:

(183) $ port install cargo
--->  Computing dependencies for cargo
--->  Building cargo
Error: Failed to build cargo: command execution failed
Error: See /Users/mathomp4/macports/var/macports/logs/_Users_mathomp4_macports_var_macports_sources_distfiles.macports.org_ports_devel_cargo/cargo/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port cargo failed

I've attached the main.log from above. As I have zero rust experience, I can't even attempt an explanation.

I can also attach info from a port -v install if needed.

(Note: I am installing macports in userspace a la ​https://github.com/citibeth/usermacports and I was able to install cargo (via a ripgrep install) with 2.4.0.)

Log file from incomplete build

I also got a build problem, but my log looks different. How can you even get this far? If I understand ​https://github.com/rust-lang/cargo/issues/3437 right, one needs cargo in order to build cargo, so cargo cannot build on a fresh MacPorts installation, right?

Replying to hmeine:

That's a different problem; see #54308.

Presumably the older version of cargo the reporter of this ticket was using did not have that requirement.

I believe this is closed since upgrading both rust and cargo. If not, feel free to reopen and attach a new build log.
