I have updated the version of sdr-core for both mac and linux to reflect the latest changes from Frank to improve the latency problem.
Also fixed a problem where the DIGU and DIGL filters were the same.
I have also deleted the build and dist directories from the repository. This seemed to be causing some problems with updates. You should manually delete these directories (and all sub directories and files) and then an update should work without any problems. A subsequent build will recreate these directories but they are now not in the repository so should not cause any problems on future updates. This is for both command line svn updates and Netbeans svn updates.
