That's not the same command as above.

Under Linux compat the order becomes:

1: /compat/linux/sbin/expr
2: /sbin/expr
3: /compat/linux/bin/expr       <- You need to create this as a link to 7
4: /bin/expr                    <- FreeBSD expr
5: /compat/linux/usr/sbin/expr
6: /usr/sbin/expr
7: /compat/linux/usr/bin/expr   <- Linux expr
8: /usr/bin/expr
...
