当我尝试安装Cabal-1.20.0.2时出现此错误：
$ cabal install Cabal-1.20.0.2.tar.gz

Warning:

(imported from System.Process.Internals):
Deprecated: "Please do not use this anymore, use the ordinary

我需要安装此软件包，因为cabal-install依赖于它。
可能是什么问题？ 谢谢！

日志文件的这一部分指出了问题：
/usr/bin/ld: cannot find -lgmp
ghc找不到libgmp。最有可能修复的是安装libgmp-dev包，例如在Ubuntu下：
sudo apt-get install libgmp-dev
