If you are trying to install SDSS binutils package for IDL on a pretty up-to-date Linux box following the instructions on SDSS site, probably you get two kinds of errors,for example:

Error: output to /lib/libmangle.a  ,permission denied.

Error: azel.s.o  not found (or "f77 : program not found " if you have not installed f77 with f2c)

首先，下载该工具包。

SDSS网页上一堆都是帮助文档，要找到下载地址还得费一番力气。从下面的链接下载所需的压缩包：

这个地址罗列了几个软件包的各个版本。这里我们只需要idlutils,选择当前的最新版比如idlutils-v5_3_0.tar，下载。
