Comment (by herbygillot):

 OK, so I just gained access temporarily to an M1 machine and was able to
 install Rust 1.51.0 from scratch without issue:

 {{{
 --->  No broken files found.
 --->  No broken ports found.
 --->  Some of the ports you installed have notes:
   libpsl has the following notes:
     libpsl API documentation is provided by the port 'libpsl-docs'.
   python39 has the following notes:
     To make this the default Python or Python 3 (i.e., the version run by
 the 'python' or 'python3' commands), run one or both of:

         sudo port select --set python python39
         sudo port select --set python3 python39
 % rustc --version
 rustc 1.51.0
 % file `which rustc`
 /opt/local/bin/rustc: Mach-O 64-bit executable arm64
 % otool -L `which rustc`

 According to your log file, the problem you're having is in compiling
 `rls`; Rust itself (`rustc`) and its standard library have built just
 fine.

 `rls` requires OpenSSL, but on your system for some reason, it's also
 looking for symbols in `libssh2`.
 I don't know why, but perhaps it may have to do with custom variants
 you've set while installing ports on your system.

 I would first try to rebuild `libssh2` from scratch.

 {{{
 sudo port uninstall libssh2
 sudo port build libssh2
 sudo port install libssh2
 }}}

 The ideal thing afterwards would be to rebuild `openssl` as well.
