#60150: portgroups cargo, cargo-fetch fail to build new port topgrade

 I'm trying to submit a new port "topgrade" (https://github.com/macports
 /macports-ports/pull/6484) using the cargo portgroup, but building fails
 and I do find the reason (log from CI attached).

 I get the exact same error when trying to build locally, but only when
 running
 {{{
 sudo port install -vst topgrade
 }}}

 The software builds just fine, though, when I cd into the work directory
 and run the build cmd from the log manually as:
 {{{
 cd /opt/local/var/macports/build/_Users_lhaeger_Documents_Source_macports-
 ports_sysutils_topgrade/topgrade/work/r-darwish-topgrade-aeb91c9
 sudo cargo clean
 sudo cargo build --release --frozen -v -j4"
 }}}

 I therefore suspect the cargo/cargo_fetch portgroups to cause the issue
 somehow.

 Would be cool if someone knowing those portgroups could look into this and
 point me into the right direction.
