WHOAMI is local to the script, so it won't be set in the run script 
leading to multilog being treated as a uid argument.

You could change this to the more readable:

echo -- generate log/run script
cat >$PWD/log/run <<EOF
#!/bin/bash
exec 2>&1
exec setuidgid $WHOAMI multilog t ./main
EOF
sudo chown -R $WHOAMI log

HTH .. Subbu
