Comment:

 cargo declares a dependency on port:libgit2. It was
 [changeset:5e87efd1c627426aadfc347e9eabf0210bcf1cba/macports-ports added
 two years ago] by @herbygillot but the commit message does not say why.

 libgit2 used to provide /opt/local/lib/libgit2.1.6.dylib but now it
 provides /opt/local/lib/libgit2.1.7.dylib. It was the responsibility of
 whoever [changeset:c00e8c728a0458fcf0e1d2c555126d6bb642feaa/macports-ports
 updated libgit2] three weeks ago to revbump all ports that link with the
 library whenever the library install_name changes, and in fact
 [changeset:08c9d92cc47d5fe2f6084e68b3165417ea20d8c9/macports-ports that
 did happen] moments later. What version of the cargo port is installed?
 (`port installed cargo`) You should not see this problem with cargo
 @0.72.2_1 or later.

 On my Monterey system cargo does not link with the libgit2 dylib but on
 yours evidently it does. I'm not sure why this difference exists.

 In addition to the dependency on the libgit2 port, cargo uses a distfile
 called libgit2-sys-0.15.1+1.6.4.crate. I'm not sure why it needs both the
 libgit2 port and its own bundled copy. Normally in MacPorts we want to use
 MacPorts copies of libraries, not bundled copies.
