请教gcc和其他

马夫

1.我在s7下安装gcc-3.3.2-sol7-sparc-local ，提示如下：
Current administration requires that a unique instance of the
<SMCgcc>; package be created.  However, the maximum number of
instances of the package which may be supported at one time on the
same system has already been met.

No changes were made to the system.
为什么庄不上呢，是不是已经有gcc了？
2.我安装vsftp源码，执行make,提示no found,是不是和没有安装gcc有关呢？
3.我安装了好多包，想卸载某个，怎么卸载呢执行pkgrm,里面有好几百个阿，是不是后面得输入包的名称，但是不知到怎么办？
问了一堆，不好意思，先谢谢了
