Trouble with SDL-Perl 2.1.3 Build process

Hi there,

I am having trouble building SDL Perl 2.1.3.

When I run:

[ 408 ] SDL_Perl-2.1.3 -: perl Build.PL
Checking whether your kit is complete...
Looks good

Checking prerequisites...
Looks good

Can't use an undefined value as an ARRAY reference at make/lib/SDL/Build.pm
line 154.



I am not sure what is wrong...  here is the offending section of code from
make/lib/SDL/Build.pm :

# save this all in a format process_xs() can understand
sub set_flags
{
       my ($self, $subsystems, $build, $defines, $includes, $links,
           $sdl_compile, $sdl_link) = @_;

       my %file_flags;

       while (my ($subsystem, $buildable) = each %$build)
       {
               my $sub_file     = $subsystems->{$subsystem}{file}{to};
               my $sub_includes = join(' ', @{ $includes->{$subsystem} } );

               $file_flags{ $sub_file } =
               {
                       extra_compiler_flags =>
                       [
                               @{ $includes->{$subsystem} },
                               split(' ',$sdl_compile),
                               @{ $defines->{$subsystem} },
                               ( defined $Config{usethreads} ?
('-DUSE_THREADS', '-fPIC') : '-fPIC' ),
                       ],
                       extra_linker_flags =>
                       [
                               @{ $links->{$subsystem}{paths} },
                               split(' ',$sdl_link),
### LINE 154 HERE: ####         @{ $links->{$subsystem}{libs} },
                       ],
               },
       }

       $self->notes( 'file_flags' => \%file_flags );
}

I am a novice at Perl and would appreciate any help.. what is wrong?

Thanks alot!
