PerMsgStatus.pm patch failed with SpamAssassin 3.001001 on FC3 with MailScanner 4.44

[ankush grover]

hey friends,

I am running  MailScanner 4.44.4 on FC3 with postfix 2.1.5. I am
trying to configure  MCP checks . I am following the settings from the
below url:

http://www.mailscanner.info/install/mcp/

find /usr/lib -name SpamAssassin -print   returns 3 directories

/usr/lib/perl5/site_perl/5.8.5/Mail/SpamAssassin
/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/Mail/SpamAssassin
/usr/lib/perl5/vendor_perl/5.8.5/Mail/SpamAssassin

1 & 3 directory both contains below files

Conf.pm, Message.pm and PerMsgStatus.pm.

SpamAssassin Version is  3.001001

When I tried to patch the 1st directory
patch < PerMsgStatus.pm.patch.3.0.0
patching file PerMsgStatus.pm
Hunk #1 FAILED at 157.
1 out of 1 hunk FAILED -- saving rejects to file PerMsgStatus.pm.rej

other 2 patches worked without any problem.

Which directory should I patch 1 or 3 and why the patch for
PerMsgStatus is failing ?

Please let me know if you need any further inputs.

Thanks & Regards
