Since you asked ...
SPOILER follows.
Add the following before your triple eval.
print;
print "\n>>>>\n";
print  eval $_;
print "\n>>>>\n";

Your $_ is first uudecoded and then packed from hex.
After the first eval you have:
my$c;$_="7072696e7420224a75737420616e6f74686572205065726c206861636b657
+25c6e223b";
while(m((..))sg){$c.=chr hex$1;}return$c;

A hex string converted to plain text. Why not using pack then?
return pack "H*", $_;

[download]
Anyway, the hex string contains the plain
'print "Just another Perl hacker\n"'
Cheers.
