The problem is that mmc2 is the INTERNAL memory card. You said you don't have an internal memory card and so it's failing to create the necessary directories and so exiting without doing anything.

Remember:
/media/mmc2 = internal memory card
/media/mmc1 = removeable memory card

I've already pointed this out elsewhere and suspect, from previous conversations, that this will be fixed in the future when the gpodder config files will be stored in a resource directory in the user's home and permit you to choose whether to store files in the internal or removable memory instead of forcing you to use internal memory for at least the config files, as it does now.

Pop in an internal memory card to fix the problem with gpodder.
