【问题描述】：
我正在尝试为 R 安装 gsl 包，据我所知，它只是 OSX Mavericks 下 GSL 的一个包装器。我已经尝试了明显的：
> install.packages('gsl')
Installing package into ‘/Users/myusername/Library/R/3.1/library’
(as ‘lib’ is unspecified)
package ‘gsl’ is available as a source package but not as a binary
Warning in install.packages :
package ‘gsl’ is not available (for R version 3.1.0)
所以我跑了
> install.packages('gsl',type = 'source')
Installing package into ‘/Users/myusername/Library/R/3.1/library’
(as ‘lib’ is unspecified)
trying URL 'http://cran.rstudio.com/src/contrib/gsl_1.9-10.tar.gz'

没有安装 GSL。哦！所以我通过 Homebrew 安装 GSL：
~ brew install gsl
==> Downloading http://ftpmirror.gnu.org/gsl/gsl-1.15.tar.gz
######################################################################## 100.0%

==> make
==> make install

再次尝试安装 R 包：

我显然是以错误的方式解决这个问题，但不确定问题到底出在哪里。
【问题讨论】：
-
我遇到了同样的问题。从 Homebrew 下载的 Mac OS 10.9.4、gcc 4.2.1、R 3.1.1 和 GSL 1.16。此外，文档 (gnu.org/software/gsl/manual/html_node/…) 中的示例程序可以毫无问题地编译（尽管我不知道如何运行/测试它，因为我对 C 一无所知）。
-
@RoyalTS。您似乎没有在 r-package 期望找到它的地方安装 GSL 包（不是 R-package gsl）。 (gnu.org/software/gsl)
-
@BondedDust 我已经通过自制软件安装了它，并且可以从命令行运行
gsl-config没有问题。我还尝试卸载自制版本并从头开始构建它，但无济于事。我收到相同的错误消息。包在哪里可以找到 GSL，我如何才能在安装过程中指向它的实际位置？ -
我没有运行 Mavericks 或自制程序，但我在某些页面中读到您可能会在终端会话中将其与
launchctl setenv PATH "/usr/local/bin:$PATH"一起修补。 -
我认为这可能会奏效，尽管只有很多额外的胶带。如果您不介意，我会将整个过程放在答案中，看看它是否也适用于其他人。
