background: subclipse seems to need the javaHL from subversion 1.2. masking subversion-1.3 does the trick but can cause this error. Steps to recreate: 1) mask >=dev-util/subversion-1.2.99 2) set keywork to ~anything for atleast apr and apr-util and required libraries 3) emerge subversion Error: (same error for apr-util if apr fixed) checking APR version... 0.9.12 wanted regex is 0\.9\.[5-9] or 1\. configure: error: invalid apr version found workaround is to mask apr and apr-util 0.9.12
Well, so don't mix stable and ~arch packages. *** This bug has been marked as a duplicate of 132904 ***
