OSX can't invoke docloader on sample database, seemingly due to wrong path

Sample databases can't be created (neither in beginning nor from settings menu) in the build 1458 for mac
dmg link: http://builds.hq.northscale.net/latestbuilds/couchbase-server-community_x86_64_2.0.0-1458-rel.dmg

In the admin console, under settings when we try to create sample buckets, beer-sample for example, there will be an error msg "request return error".

The log for this error:
