Alan - this "fix" breaks linkage on Ubuntu 14.10 with the error Linking CXX executable wxPLViewer /usr/bin/ld: CMakeFiles/wxPLViewer.dir/__/drivers/wxwidgets_comms.cpp.o: undefined reference to symbol 'shm_unlink@@GLIBC_2.2.5' /lib/x86_64-linux-gnu/librt.so.1: error adding symbols: DSO missing from command line Uncommenting line 88 in utils/CMakeLists.txt to explicitly link in the rt library fixes this. o I'm surprised this is a difference between Ubuntu and Debian since they are usually similar. I would suggest we leave this uncommented since it seems to treat the problematic MacOSX case separately anyway.
