I also experience this problem; switching nodejs versions (0.4.11-pre == v0.4 branch, 0.4.10 and 0.5.2) did not have any effect.
When compiling with: bin/cljsc samples/nodehello.cljs '{:target :nodejs :optimizations :simple :pretty-print true}' > nodehello.js the (first) relevant line for this error seems to be: goog.global.Date.prototype.cljs$core$IEquiv$ = !0; I don't get why this is goog.global.Date and not goog.date.Date, or where the definition should actually come from; somehow it smells like config trouble or (most likely) user error.
