Git-windows and git-svn?

Hello,

I would like to try git on Windows together with git-svn, I downloaded 
  Git-1.5.3-preview20071027.exe and tried:

yns@xxx /d/devel/lyx/git/trunk
$ git-svn init svn://svn.lyx.org/lyx/lyx-devel/trunk
Useless use of a constant in void context at /bin/git-svn line 848.
Can't locate Digest/MD5.pm in @INC (@INC contains: /lib 
/usr/lib/perl5/5.6.1/msy
s /usr/lib/perl5/5.6.1 /usr/lib/perl5/site_perl/5.6.1/msys 
/usr/lib/perl5/site_p
erl/5.6.1 /usr/lib/perl5/site_perl .) at /bin/git-svn line 2420.
BEGIN failed--compilation aborted at /bin/git-svn line 2420.

Is there something I am doing wrong?

Thanks in advance for any help,
Abdel.
