git-svn: Can't locate SVN/Core.pm

To import subversion repository to git, I get the following problem

git-svn clone http://dev.com/code/example/trunk example
Can't locate SVN/Core.pm in @INC (@INC contains: /usr/local/lib/perl5/site_perl /opt/local/lib/perl5/5.8.8/darwin-2level /opt/local/lib/perl5/5.8.8 /opt/local/lib/perl5/site_perl/5.8.8/darwin-2level /opt/local/lib/perl5/site_perl/5.8.8 /opt/local/lib/perl5/site_perl /opt/local/lib/perl5/vendor_perl/5.8.8/darwin-2level /opt/local/lib/perl5/vendor_perl/5.8.8 /opt/local/lib/perl5/vendor_perl .) at /usr/local/bin/git-svn line 29.

Installing of the perl subversion binding solved this problem.
