Question

我正在尝试在OS X上使用Math::GSL安装cpan。我通过自制程序编译并安装了GSL本身，所以这一切都很好。出于某种原因，编译器在尝试构建GSL perl模块时会发出大量警告，最后在发生错误后死亡。我认为这是因为这个库应该用gcc构建（我已经开始使用Gentoo了。）但是我不确定如何将cpan指向gcc。

这是错误的样子：

 ... We get another 20 or so beautiful clang warnings after this one, and then this:

... Another error after this, and then it dies.

有谁知道如何解决这个问题？我正在运行用perlbrew for OS X 10.9构建的perl v5.18.1。我有一个关于整件事的要点here。
