[CentOS] Openwebmail emergency (Perl)

Thanks. Too bad I cannot speak Perl.

Here's the info:

[root at mail]# uname -a
Linux mail.greenspot.fi 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 05:09:20 
EDT 2010 i686 i686 i386 GNU/Linux


[root at mail]# rpm -q perl-Compress-Raw-Zlib perl-IO-Compress 
perl-IO-Compress-Zlib perl
perl-Compress-Raw-Zlib-2.030-1.el5.rf
perl-IO-Compress-2.030-2.el5.rf
package perl-IO-Compress-Zlib is not installed
perl-5.8.8-32.el5_5.2
[root at mail tiina]#


This could be caused by something in Openwebmail. I found info that 
whenever memGzip is not successful, it returns undef - this probabvly 
means "undefined subroutine", which is what Openwebmail now tells me.

http://search.cpan.org/~pmqs/IO-Compress-2.030/lib/Compress/Zlib.pm


Maybe this will help - here is the offending Openwebmail function:

sub httpprint {
    my ($r_headers, $r_htmls)=@_;
    if (is_http_compression_enabled()) {
       my $zhtml=Compress::Zlib::memGzip(join('',@{$r_htmls}));
       if ($zhtml ne '') {
          print httpheader(@{$r_headers},
                           '-Content-Encoding'=>'gzip',
                           '-Vary'=>'Accept-Encoding',
                           '-Content-Length'=>length($zhtml)), $zhtml;
          return;
       }
    }
    my $len; foreach (@{$r_htmls}) { $len+=length($_); }
    print httpheader(@{$r_headers}, '-Content-Length'=>$len), @{$r_htmls};
    return;
}

- Jussi
