Probably works fine, but I use Mac OS X. The AVARISP only has USB, so  
there might be issues if you can't get USB to work. I think it works  
well, from what I've inferred.

The avr-gcc toolchain, avr-gdb, avarice. I've never gotten avrdude to  
work, but I've been able to do all I need with avarice (note that it  
uses a different set of pins; no SPI).

You want to get the toolchain and related tools. I used this page as  
a guide. Things I did differently: I put everything under /usr/local/ 
avr (using --prefix=/usr/local/avr for the ./configure steps), and I  
got the latest version of each package. I also configured gcc to  
build both C and C++ compilers. I didn't bother with uisp (it's been  
superseded by avrdude) The page is Mac OS X-specific, but I suspect  
you'll need to make very few changes to get it to work.
