Ubuntu系統sh命令引起編譯問題

主機系統：Ubuntu 10.10

交叉編譯iptables-1.4.10時，出現以下錯誤：

eval: 1: libtool_args+=: not found
eval: 1: compile_command+=: not found
eval: 1: finalize_command+=: not found
eval: 1: libtool_args+=: not found
eval: 1: compile_command+=: not found
eval: 1: finalize_command+=: not found
eval: 1: libtool_args+=: not found
eval: 1: compile_command+=: not found
eval: 1: finalize_command+=: not found
eval: 1: libtool_args+=: not found
eval: 1: compile_command+=: not found
eval: 1: finalize_command+=: not found
eval: 1: libtool_args+=: not found
eval: 1: compile_command+=: not found
eval: 1: finalize_command+=: not found
eval: 1: libtool_args+=: not found
eval: 1: compile_command+=: not found
eval: 1: finalize_command+=: not found

解決方法：cd /bin; rm sh; ln -s bash sh

在ubuntu發行版下,查看sh命令。
$ cd /bin
$ ls -l
lrwxrwxrwx 1 root root 4 sh -> dash
實際上，sh命令鏈接的是dash(Debian-shell)。
