I think you will need a different instance of Abe for each altcoin. It doesn't support all altcoins, and some will need special setup because of the different algorithms. You can find which coins it supports and what needs to be installed on the project README file. If you need help, you might be able to PM or email the main developer of the project. His profile is here:
