%%VERSION%% is used instead of %%VER%% in pkg-plist. This results in the staging part failing.
This belongs to office@ so I will CC them, but this is a "just fix it" type of bug so I'll not set the assignment and move it to patch-ready.
Your tree is outdated.
Look at the current version of pkg-plist:

It already has %%VER%%, not %%VERSON%% so I suspect your base port is very old, at least more than 7 months old.
closing as invalid.
