rpm无法安装问题---vgagl.h安装

[redopium]

为了安装vgagl.h库，我下载了svgalib-devel-1.9.21-5.i386.rpm for fedaro4，但在安装时发生情况如下，不知何解

[root@localhost ~]# rpm -ivh /home/ro/svgalib-devel-1.9.21-5.i386.rpm
warning: /home/ro/svgalib-devel-1.9.21-5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 1ac70ce6
error: Failed dependencies:
svgalib = 1.9.21-5 is needed by svgalib-devel-1.9.21-5.i386


直接双击安装在99%时出现如下画面：<a href=http://www.pcpop.net/st.png>http://www.pcpop.net/st.png</a>

不得其解，请高手指点！
