You can find the download link here:
http://dl.dropbox.com/u/67145446/Unvanq ... uished.dmg
Make sure you have downloaded pak8.pk3 (and vms-0.9.0.pk3) (and other paks if you haven't already) from here:
http://sourceforge.net/projects/unvanqu ... es/Assets/
OR
http://unvanquished.net/downloads/main/
Place them into your ~/Library/Application\ Support/Unvanquished/main folder. Make sure you have earlier vms removed (e.g. vms-0.8.0.pk3) from this folder.
Enjoy
P.S. If you would like a mirror link because Dropbox does not work for you, please do not hesitate to request for one.
