There is no different memory allocator or anything like that like on Windows, so the debug/release versions are fully interchangeable. So you do not *need* the debug version. Whether or not debug is replaced by release in the absence of the debug versions for the COLLADA plugin, I do not know, though. In general, on a non-Windows platform if you are not going to debug the plugin itself or OSG, it is perfectly fine to build only release versions. The consequence will be that e.g. in a backtrace you wouldn't be able to see the exact line of the code if a crash occurs in the plugin (the debug symbols are gone), but that is all. Even that could be alleviated by building as RelWithDebInfo (release, but not stripped, keeps debug symbols). The only issues will be be that certain optimizations that reorder code interfere with debugging (gdb shows wrong line) and the files are larger.
