Found the issue. I built a few libraries from source earlier in /usr/local/lib . indicator-datetime-service found those libraries before the system libraries in /usr/lib for some reason. It shouldn't have done that.
One of those libraries pulled in the old libical.so.0 dependency which was no longer available. When I deleted all the GNOME/Evolution related libraries in /usr/local/lib I could start indicator-datetime-service again and my clock shown up.
Why would indicator-datetime-service load libraries from /usr/local/lib before /usr/local if they have the same library versions? Isn't that a bug?
