If you can get it all to work, create a hg bundle and mail it to this 
list. Instructions on how to create a bundle can be found at the end of 
the DOLFIN manual.

Apparently there are some serious technical obstacles with gcc 4.x and 
Cywgin, so I don't expect that this will be trivial.

VirtualBox (http://www.virtualbox.org) is free and very easy to use. My 
experience is that if you have a relatively new processor and enable the 
virtualisation option in the BIOS, performance is near native.
