Running over CentOS 6.4, I had just successfully follow the steps:

- Install curl-devel and libxml with the Linux command line:

```
$ sudo yum install curl curl-devel
$ sudo yum -y install libxml2 libxml2-devel
```

- On R console, restart the R session and install the RCurl and XML package:

```
>> install.packages("RCurl")
>> install.packages("XML")
```

- Load the libraries:

```
>> library(RCurl)
>> library(XML)
```

Hope this save you a day!
