On 10.9 builder only, several port updates are failing like this: Error: Failed to activate curl: Image error: /opt/local/bin/curl already exists and does not belong to a registered port. Unable to activate port curl.
For example: https://github.com/macports/macports-ports/commit/3d71c6828c4410228ffbab027235c526f9277916#commitcomment-164187129 This looks like a common problem on the 10.9 builder, and is not specific to the target port updates. I am posting this only to prevent redundant debugging. It looks like this was already reported appropriately. I do not personally know the exact cause of this problem.
