I'm not personally familiar with the PostScript::Simple module,
but I just looked it up on CPAN and it doesn't look like the
'new' method can fail to return a reference (aside from maybe out
of memory).
The error you're getting certainly does suggest that $ps is
undefined, however. Try using Data::Dumper to print it to be
sure.
Also, note that indirect-object notation is frowned upon,
so you should explicitly call the 'new' class method instead.
Make sure you're also using the 'strict' and 'warnings' pragmas
so that Perl can point out any subtle mistakes that you may have
made. :)
use strict;
use warnings;
use Data::Dumper;
my $ps = PostScript::Simple->new(papersize => 'A4',
colour => 0,
eps => 0,
units => 'mm');
print Dumper $ps;

HTH,
