I don't know exactly how things are run but on by amd64 debian system I have under / the directories drwxr-xr-x 15 root root 12288 2007-12-19 09:34 lib lrwxrwxrwx 1 root root 20 2007-10-12 01:01 lib32 -> /emul/ia32-linux/lib lrwxrwxrwx 1 root root 4 2007-10-12 00:32 lib64 -> /lib I don't anything special to run the 32 bit stuff though ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
