mysql的librt.so.1问题请教!

forrestrun

在solaris 7下面安装了mysql4.0.12的binary包（由于没有for 7的，就使用for8的包了），但是运行的时候出现错误，提示librt.so.1错误。

mysql的.err日志：

030409 10:15:40 mysqld started
ld.so.1: /usr/local/mysql-max-4.0.12-sun-solaris2.8-sparc/bin/mysqld: fatal: librt.so.1: version `SUNW_1.2' not found (required by file /usr/local/mysql-max-4.0.12-sun-solaris2.8-sparc/bin/mysqld)
030409 10:15:41 mysqld ended

我查看相关的动态支持文件提示：
bash-2.03# ldd /usr/local/mysql/bin/mysqld
librt.so.1 =>; /usr/lib/librt.so.1

该怎么办呢？
