>From problems you were having previously I'm assuming that you have an older version of APR installed somewhere on Path and that is getting found instead of the 1.3 version you built and installed in /usr/local most likely in /usr/lib. The best solution is to build and install APR over the install that you currently have in /usr so that you don't have to muck around with all these path changes to get the client to build and run. Barring that you need to alter your environment such that the version of APR found first by the loader is the 1.3 version. You can install an APR 1.3 over an older version of APR 1.x since the APR version guidelines state that they are always backwards compatible across major version numbers.
