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.

Install ruby-pg (PostgreSQL ruby driver) On Leopard

It is not so easy to install ruby-pg in Leopard

Felix:~ sunfmin$ sudo gem install ruby-pg
Building native extensions.  This could take a while...
ERROR:  Error installing pg:
    ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb install pg

        ===========   WARNING   ===========

        You are building this extension on OS X without setting the 
        ARCHFLAGS environment variable, and PostgreSQL does not appear 
        to have been built as a universal binary. If you are seeing this 
        message, that means that the build will probably fail.

        Try setting the environment variable ARCHFLAGS 
        to '-arch i386' before building.

        For example:
        (in bash) $ export ARCHFLAGS='-arch i386'
        (in tcsh) % setenv ARCHFLAGS '-arch i386'

        Then try building again.
