I was able get php and perl to play together with blowfish using cipher block chaining. The
blowfish key needs to be atleast 8 chars (even though blowfish min is 8 bits, perl didn't like
keys smaller than 8 chars) and max 56. The iv must be exactly 8 chars and padding needs to be null
because php pads with nulls. Also, php needs libmcrypt >= 2.4.9 to be compatible with perl.
PERL

use Crypt::CBC;
$cipher = Crypt::CBC->new( {'key' => 'my secret key',
'cipher'=> 'Blowfish',
'iv' => '12345678',
'regenerate_key' => 0,
'padding' => 'null',
'prepend_iv' => 0
});
$cc = 'my secret text';
$encrypted = $cipher->encrypt($cc);
$decrypted = $cipher->decrypt($encrypted);
print "encrypted : ".$encrypted;
print "<br>";
print "decrypted : ".$decrypted;

$cc = 'my secret text';
$key = 'my secret key';
$iv = '12345678';
$cipher = mcrypt_module_open(MCRYPT_BLOWFISH,'','cbc','');
mcrypt_generic_init($cipher, $key, $iv);
$encrypted = mcrypt_generic($cipher,$cc);
mcrypt_generic_deinit($cipher);
mcrypt_generic_init($cipher, $key, $iv);
$decrypted = mdecrypt_generic($cipher,$encrypted);
mcrypt_generic_deinit($cipher);
echo "encrypted : ".$encrypted;
echo "<br>";
echo "decrypted : ".$decrypted;
