I've had no problem compiling an earlier version under VS2005/.NET 2.0, though I needed to pick up a few dependencies from other projects first. It took a while to get everything. It would be nice if someone would compile the current version and post it on codeplex.
Another option, if you just need a flexible search engine for your site of <1000 nodes, is XSLTsearch. It is fully documented and available at
