Hi ,
I am not sure that it will help , but

for environment variables you can use %ENV  hash

and if you want to define some places with perl modules , you can  use
@INC array

here is an example
#!/usr/bin/perl

foreach my $val (keys (%ENV) ) {
        print $ENV{$val};
}

push (@INC,'/usr/lib/my_modules');

foreach my $val(@INC) {
        print "$val\n";
}

$perl env.pl
DCOPRef(konsole-3234,session-6)/local/adm/.Xauthority\h:\w\$ local| 
/usr/bin/lesspipe 
%s/tmp/ssh-HUJSRj3179/agent.3179/stable/rooten_US.UTF-8root/usr/lib/jvm/jdk1.6.0_05/jreroot1;31/usr/bin/lesspipe

%s 
%s3/usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin:/usr/bin/X11:/usr/lib/jvm/jdk1.6.0_0
<skip>
/usr/local/lib/perl/5.10.0
/usr/local/share/perl/5.10.0
/usr/lib/perl5
/usr/share/perl5
/usr/lib/perl/5.10
/usr/share/perl/5.10
/usr/local/lib/site_perl

or another example  (best) which i've found here 
http://www.devdaily.com/perl/edu/articles/pl010015/

#!/usr/bin/perl

use lib "/home/george/modules";

print "\@INC is @INC\n";

$perl inc.pl
@INC is /home/george/modules /etc/perl /usr/local/lib/perl/5.10.0 
/usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 
/usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .
