I had originally posted regarding an error when trying to install package -
GenABEL - it has now become clear that R is not able to connect to the net.
Below are a couple of things I've tried with the resulting errors

I am running R 2.6.2 on Linux e15 X86

How can I fix this?  Thank you!

1)  download.file("http://www.nytimes.com", destfile<-tempfile())

trying URL 'http://www.nytimes.com'
Error in download.file("http://www.nytimes.com", destfile <- tempfile()) :
  cannot open URL 'http://www.nytimes.com'
In addition: Warning message:
In download.file("http://www.nytimes.com", destfile <- tempfile()) :
  unable to resolve 'www.nytimes.com'

2) install.packages("GenABeL", lib= "/home/software/GenABEL", dep = TRUE,
method = "wget") 

Selection: 43
sh: wget: command not found
Error in gzfile(file, "r") : unable to open connection
