let's start by the beginning.
First, get rid of that line: gamedll "podbot\podbot.dll"
Second, empty your plugins.ini file and see if metamod loads at all (without any plugin) by typing "meta list" in the console.
Third, in the plugins.ini file add the line corresponding to POD-Bot_mm and see if metamod loads the bot.
Fourth, in the plugins.ini add the line corresponding to AMX and see if AMX loads at all. DO NOT LOAD ANY AMX PLUGIN.
And finally, add your AMX plugins one after the other until everything works. Test out your setup each time you add a new AMX plugin, this way if one particular plugin is causing the crash you'll know which one it comes from.
*edit* oops, sorry TGM, I didn't see your post
