1) pull and build go (On OSX 10.5 if it matters.)
2) gofmt gotrace.go

gotrace.go:164:21: expected ')', found '{'
gotrace.go:166:9: expected operand, found 'return'
gotrace.go:168:5: expected declaration, found 'IDENT' litColor
gotrace.go:169:5: expected declaration, found 'IDENT' totalColor
gotrace.go:170:5: expected declaration, found 'return'
gotrace.go:171:1: expected declaration, found '}'

The line that causes the problem is:

    if intersect(Ray{p, vec3mulf(s.light, -1.0)}, s.g).distance < infinity {

It's the 'Ray{...}' that's causing the problem.
