Mac で git svn すると Can’t locate SVN/Core.pm エラー

Catalina にアップデートすると svn コマンドが使えなくなるという話があり、Homebrew で再セットアップしたのだが、git svn コマンドだとエラーが。

Can't locate SVN/Core.pm in @INC (you may need to install the SVN::Core module) (@INC contains: /usr/local/Cellar/git/2.29.2/share/perl5 /Applications/Xcode.app/Contents/Developer/Library/Perl/5.18/darwin-thread-multi-2level /Library/Developer/CommandLineTools/Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.4 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at /usr/local/Cellar/git/2.29.2/share/perl5/Git/SVN/Utils.pm line 6.

/usr/local/opt/git/libexec/git-core/git-svn を開いて1行目を #!/usr/local/bin/perl に変更すると解消された。こんなんでいいんかな…。
