Looking at the port select code, it just tries to create each symlink in turn. There isn't any special error handling code to deal with the case that a symlink can't be created; if that happens, an error will occur and MacPorts will exit. Any symlinks that were already successfully created will remain on disk. This would leave you with an incomplete or possibly even inconsistent set of symlinks. 

Somebody should fix the bug in the mysql57 port. If you'd like to do so, you can submit a pull request in macports-ports. 

It might be reasonable to add error handling to port select so that it reverses any partial work that it had completed if an error occurs. If you'd like to add that error handling, it can be done via a pull request in macports-base.
