无法在 Red hat linux 上安装 rgdal 和 rgeos R 库

我编译时出错rgdal adn rgoes我们的 redhat linux 机器上的包。我尝试做一些研究，但找不到可能的解决方案。您能帮我解决这个问题吗，因为这对我来说非常重要。

download the source from  http://www.gdal.org/
If you have installed the GDAL libraries, then make sure that
gdal-config is in your path. Try typing gdal-config at a
shell prompt and see if it runs. If not, use:
--configure-args='--with-gdal-config=/usr/local/bin/gdal-config'
with appropriate values for your installation.

在 Fedora 20 上你需要安装geos and geos-devel !

sudo yum install geos geos-devel

之后，R 中的编译工作顺利！
