I upgraded to Arduino 1.5.7 in hopes of using the command line interface for a larger project. However, the old package I was using to program the ATTiny85 chip with the Sparkfun Tiny AVR Programmer no longer works. I'm getting the following error:

Third-party platform.txt does not define compiler.path. Please report this to the third-party hardware maintainer.

Does a package exist that will allow me to program the chip in 1.5.7?

You can download a version of arduino-tiny for IDE 1.5.x from here.
