Problem with subversion update

[Steven Rogers]

Howdy all,

I'm trying to update my subversion installation from subversion  
1.3.2_0+mod_dav_svn and I'm getting the following error - I've  
googled around for hints, but so far nothing specific - any thoughts  
appreciated:

steve$ sudo port upgrade subversion +mod_dav_svn
