[R-SIG-Mac] Fwd: XML crash

[Duncan Temple Lang]

Hi Adrian

 (Busy couple of days, so apologies for not replying to your off-list email.)

 What is the output from

 library(XML)
 libxmlVersion()

 On my OSX machine(s), I get the same as you got on Windows - i.e. failed to load HTTP resource.
 But I have installed newer versions of libxml2 on my machines.
