Yosemite broke my git svn

Previously on Mavericks:

$ git svn rebase
Can't locate SVN/Core.pm in @INC (@INC contains: /usr/local/Cellar/git/1.8.4/lib /Library/Perl/5.16/darwin-thread-multi-2level /Library/Perl/5.16 /Network/Library/Perl/5.12/darwin-thread-multi-2level /Network/Library/Perl/5.16 /Library/Perl/Updates/5.16.4 /System/Library/Perl/5.16/darwin-thread-multi-2level /System/Library/Perl/5.16 /System/Library/Perl/Extras/5.16/darwin-thread-multi-2level/System/Library/Perl/Extras/5.16 .) at /usr/local/Cellar/git/1.8.4/libexec/git-core/git-svn line 41.

Solution: since the system Perl 5.16 contains SVN::Core, link it in from /Applications/Xcode.app/Contents/Developer/Library/Perl/5.16.

Now on Yosemite:

$ git svn rebase 
Can't locate SVN/Core.pm in @INC (you may need to install the SVN::Core module) (@INC contains: /usr/local/git/lib/perl5/site_perl /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl /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/5.18.2 /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 /Applications/SourceTree.app/Contents/Resources/git_local/lib/perl5/site_perl/Git/SVN/Utils.pm line 6.

Solution? We don’t have Perl 5.18 from Xcode.app – so instead just install SVN from CPAN.

$ sudo cpan SVN::Core
...
$ git svn rebase
error: git-svn died of signal 11

Hey, a feature! Now it segfaults! I can’t be bothered to debug this properly, but got around it by changing the shebang in git-svn to require perl5.16. Yuck.

locate git-svn
emacs -q .../git-svn

EDIT: apparently a reinstall also fixes it.
