[COMPASS-SUPPORT] Compile error with sensorfilter-deadlockfree.slim example

Using Compass for the first time, I get the following error loading the example in section 7.3 of the user manual; /home/compasseval/Desktop/COMPASS-toolset/tools/examples/sensorfilter-deadlockfree.slim:107: (D-7) FDIR type tags port "detected" as observable. detected: out data port bool default false observable; ^ Compiling 'Desktop/COMPASS-toolset/tools/examples/sensorfilter-deadlockfree.slim'... ERROR Compiling 'Desktop/COMPASS-toolset/tools/examples/sensorfilterErr.slim'... OK Is that in fact a slim file error? I'm running Compass-vm-2.3 on VMware Player -Chris Wilkinson-
