There are a few things that need to be done to get it working:
Firstly, in 4 Perl scripts (checksetup.pl, testserver.pl, index.cgi and Bugzilla.pm) you need to add the path to the alternative Perl modules that cPanel has installed:
BEGIN { my $homedir = ( getpwuid($>) )[7]; my @user_include; foreach my $path (@INC) { if ( -d $homedir . '/perl' . $path ) { push @user_include, $homedir . '/perl' . $path; } } unshift @INC, @user_include; }
When you run the ./checksetup.pl file you may need to specify more options, especially if your Perl installation constantly runs out of memory:
./checksetup.pl --no-templates --make-admin
and all should work.
