Cant compile for Uno
Googling some of those terms (especially "prog_uint16_t bitrate_table"), it looks like you may have an old version of the library, since that code was removed back in 2012.

This appears to be the latest version: https://github.com/madsci1016/Sparkfun-MP3-Player-Shield-Arduino-Library

I would start by grabbing that (using the "Download ZIP" button if you don't use git/GitHub) and trying the example from there. The examples are within the SFEMP3Shield folder.
