I'm just being carefull. Historically, Linux has been bad about maintaining binary compatibility for teh fringes of its ABI. When I released the binary only ObjectBuilder, it was good for about 3 months before the ABI changed enough so that it couldn't run.... And they didn't bump the major rev to reflect this breakage (they were using the C++ streams for stdio, which left C++ mangled names exposed to all application programs :-(. BTW, is it possible to have multiple versions of the linux libraries installed? I've recently given some thought to seeing if I could get ObjectBuilder running again...
