configure: WARNING: APR not found
The Apache Portable Runtime (APR) library cannot be found.
Please install APR on this system and configure Subversion
with the appropriate --with-apr option.

You probably need to do something similar with the Apache
Portable Runtime Utility (APRUTIL) library and then configure
Subversion with both the --with-apr and --with-apr-util options.
