lenny amd64 configure错误 "configure: error: You don't have forkpty&

asmart

netinst 的iso安装的lenny amd64 最小化  以及后来安装了 gcc g++ make automake autoconf apache2 bzip2

接下来在configure过程报错 出错信息如下

在此之前 从没发现过这个问题 " checking for forkpty in -lutil... no "
是64位系统的通病还是什么  

我需要安装什么东西才能让这个该死的forkpty出来呢  

man fork和man forkpty都没结果 ， 32位系统无此问题
