[rt-users] RT2 Installation with Mod_Perl assistance required :: RT dies after enter username and password

[John]

Sorry to bother everyone. I am going around in circles so if someone 
could just point me in the right direction, I can let go of my tail.

Mandrake 8.1 (I know a little old, it is behind a firewall on a local 
network)
Apache 1.3.31 + Mod_Perl
RT-2-0-15

1/ Dependencies installed ok (with exception of Apache::Cookie which 
gave me some trouble with the dependancy Apache::Test)
2/ Fixed Apache to mod_perl savvy (I think) and my only confirmation is 
from the apache log:
... [notice] Apache/1.3.31 (Unix) mod_perl/1.29 configured -- resuming 
normal operations
3/ Had a permission issue on the log file, fixed it and now...
4/ Login screen comes up ok (except RT image top left - minor issue). If 
you enter the wrong username or password it tells you. BUT when the 
right username or password is entered you get a SYSTEM ERROR with the 
following detail

The section of  Handle.pm where it fails for me (as per above) is as 
follows, I don't know if this helps you point out where it is going 
wrong or not...but I thought I would include incase it is helpful.

<Handle.pm_snip>
863  sub _BuildJoins {
   864      my $self = shift;
   865      my $sb   = shift;
   866      my %seen_aliases;
   867
   868      $seen_aliases{'main'} = 1;
   869
   870      my $join_clause = $sb->{'table'} . " main ";
   871
   872      my @keys = ( keys %{ $sb->{'left_joins'} } );
   873      my %seen;
   874
   875      while ( my $join = shift @keys ) {
   876          if ( $seen_aliases{ 
$sb->{'left_joins'}{$join}{'depends_on'} } ) {
   877              $join_clause = "(" . $join_clause;
   878              $join_clause .=
   879                $sb->{'left_joins'}{$join}{'alias_string'} . " ON (";
   880              $join_clause .=
   881                join ( ') AND( ',
   882                  values %{ $sb->{'left_joins'}{$join}{'criteria'} 
} );
   883              $join_clause .= ")) ";
   884
   885              $seen_aliases{$join} = 1;
   886          }
   887          else {
   888              push ( @keys, $join );
   889              die "Unsatisfied dependency chain in Joins @keys"
   890                if $seen{"@keys"}++;
   891          }
   892
   893      }
   894      return ( join ( ", ", ( $join_clause, @{ $sb->{'aliases'} } 
) ) );
   895
   896  }
</Handle.pm_snip>

Unfortunately there is no further information in the RT log file or 
Apache error log file... they both think things are fine for some reason...
Am I looking for another permission issue? or is it an apache config 
problem? I am using Apache's DocumentRoot as follows:

<httpd.conf_snip>
DocumentRoot /opt/rt2_innes/WebRT/html
ServerName rt.example.com
# PerlModule Apache::DBI
PerlRequire /opt/rt2_innes/bin/webmux.pl
<Location />
SetHandler perl-script
PerlHandler RT::Mason
</Location>
</httpd.conf_snip>

PerlModule Apache::DBI (as predicted in RTFM) stopped Apache from starting.

I have now tried Multiple installs of:
OpenBSD, FreeBSD and now Mandrake. This time I think I am close...I can 
almost see that nice RT screen....but no cigar yet :-(

Any help, advice,  solutions would be much appreciated... sleep patterns 
way outa whack for over a week now...

Thanks to anybody who takes the time even if you are unable to assist in 
my dilema.

Kind regards,

John
