为什么rgdal无法加载RStudio（0.94.110）但不能加载R（2.13.2）？

abarbour% R

R version 2.13.2 (2011-09-30)
Copyright (C) 2011 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

[编辑删除无关信息]

> library(rgdal)
Loading required package: methods
Loading required package: sp
Geospatial Data Abstraction Library extensions to R successfully loaded

Loaded PROJ.4 runtime: Rel. 4.7.1, 23 September 2009, [PJ_VERSION: 470]
Path to PROJ.4 shared files: (autodetected)

但是，在 RStudio 中：

R version 2.13.2 (2011-09-30)
Copyright (C) 2011 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

[再次，编辑]

> library(rgdal)
Loading required package: methods
Loading required package: sp
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared object '/Users/abarbour/kook.processing/R/PACKAGES/rgdal/libs/x86_64/rgdal.so':

  Expected in: /Library/Frameworks/R.framework/Resources/lib/libgcc_s.1.dylib

Error: package/namespace load failed for 'rgdal'

有谁知道为什么会这样？是否有某种RStudio我不知道的默认值？

请注意，它rgdal是使用以下命令安装的，已经安装了 KyngChaos（GDAL Complete 框架）：

sudo R CMD INSTALL --configure-args='--with-gdal-config=/Library/Frameworks/GDAL.framework/unix/bin/gdal-config --with-proj-include=/Library/Frameworks/PROJ.framework/unix/include --with-proj-lib=/Library/Frameworks/PROJ.framework/unix/lib' rgdal_0.7-1.tar.gz

来自支持人员的 Josh 致谢RStudio（参见讨论）。

从内部RStudio：

> setRepositories()

[输入“1 2”]

> install.packages("rgdal")
> library(rgdal)

给出正常的负载行为：
