The path returned by ports.cgi for e.g. inclusion in the URLs in the FreeBSD Ports Search results pages has not been updated to point to the GIT repository instead of SVNWEB.
The same URL change is required in man.cgi.
I do not know how cgi-style.pl is used on the web-site, but it also has a reference to svnweb.freebsd.org (and thus SVN) that should be changed to point at the Git repository.
