Since upgrading (and swaping hard-drives) I am now unable to run BYOND.
I extract it, copied the required .so files to the /usr/lib folder (but oddly enough, only core files for BYOND, the thing it's asking isn't even in the installation zip!)
# ./DreamSeeker
./DreamSeeker: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory
