so.. is mysql yust removing out those first 2 zero`s?... i`m having a hard time believing that..
oke.. i wrote a tiny php script to make this clear:

<?php

    if (5.6 < 5.00504)
    {
        echo 'not what i would have expected<br />';
    }
    else
    {
        echo 'see, 5.00504 is smaller than 5.6 like i said<br />';
    }

    if (1.1 == 1.01)
    {
        echo 'not what i would have expected<br />';
    }
    else
    {
        echo 'see, they 1.1 is not equal to 1.01<br />';
    }

?>

the result on my php (5.2.1) is: "see, 5.00504 is smaller than 5.6 like i said" and "see, they 1.1 is not equal to 1.01"
those are the facts that are gonna be used in the dep checker. though i will probably need to break the recursive loop quite a few time if those strange version numbers like 1.1b2 occur...
so jesse... how is your math going? ;)

Actually, 5.6 is smaller.  5 and 5 is compared, then 00504 and 6 is compared.
00504 actually becomes 504 which is higher than just 6 and thus wins.
