无法在Ubuntu 12.04上安装R3.0.2的XML包

我无法在Ubuntu12.04 64位上的R3.0.2上安装XML包，请参见下面的错误。我在网上搜索并安装了xml2-dev。它已安装，但R在库中找不到

如前所述，我已经安装了xml2：

sudo apt-get install libcurl4-openssl-dev libxml2-dev

kayhan@lemongrass:~$ locate libxml2.so
/usr/lib/x86_64-linux-gnu/libxml2.so.2
/usr/lib/x86_64-linux-gnu/libxml2.so.2.7.8

存储库中的r-cran-xml在r 3.0之前构建的b/c中没有用处。知道如何安装XML吗？这是一个非常重要的包，许多其他包都依赖它

谢谢

原来my Python Enthow设置有冲突！！可能是因为它通过修改ldu-LIRARY使一些库过载。在.bashrc中，我指出：

VIRTUAL_ENV_DISABLE_PROMPT=1 source /[....]/Enthought/Canopy_64bit/User/bin/activate

并安装了它，它的工作！奇怪的冲突

您应该将更新作为答案发布。
