在RHEL上安装RPM包时，可能会遇到循环依赖的问题，例如：RPM包1依赖于包2，包2依赖于包3，包3又依赖于包1，好像就没办法装下去了。下面就是一例：

[root@RHEL rpm]# rpm -ivh mesa-libGL-devel-6.5.1-7.7.el5.x86_64.rpm 

warning: mesa-libGL-devel-6.5.1-7.7.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

error: Failed dependencies:


        libX11-devel is needed by mesa-libGL-devel-6.5.1-7.7.el5.x86_64

[root@RHEL rpm]# rpm -ivh libX11-devel-1.0.3-9.el5.x86_64.rpm 

warning: libX11-devel-1.0.3-9.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

error: Failed dependencies:

        libXdmcp-devel is needed by libX11-devel-1.0.3-9.el5.x86_64

        xorg-x11-proto-devel >= 7.1-2 is needed by libX11-devel-1.0.3-9.el5.x86_64

[root@RHEL rpm]# rpm -ivh libXdmcp-devel-1.0.1-2.1.x86_64.rpm 

warning: libXdmcp-devel-1.0.1-2.1.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

error: Failed dependencies:

You have new mail in /var/spool/mail/root

[root@RHEL rpm]# rpm -ivh xorg-x11-proto-devel-7.1-9.fc6.x86_64.rpm 

warning: xorg-x11-proto-devel-7.1-9.fc6.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

error: Failed dependencies:

        mesa-libGL-devel is needed by xorg-x11-proto-devel-7.1-9.fc6.x86_64

[root@RHEL rpm]# rpm -ivh mesa-libGL-devel-6.5.1-7.7.el5.x86_64.rpm 

warning: mesa-libGL-devel-6.5.1-7.7.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

error: Failed dependencies:

        libX11-devel is needed by mesa-libGL-devel-6.5.1-7.7.el5.x86_64

这个时候，把这些包一起安装就好了：

rpm -ivh mesa-libGL-devel-6.5.1-7.7.el5.x86_64.rpm libX11-devel-1.0.3-9.el5.x86_64.rpm libXdmcp-devel-1.0.1-2.1.x86_64.rpm xorg-x11-proto-devel-7.1-9.fc6.x86_64.rpm mesa-libGL-devel-6.5.1-7.7.el5.x86_64.rpm

有人说要加上--aid的参数，我没加也可以通过。
