[R-SIG-Mac] ‘package ‘XML’ is not installed for 'arch=x86_64'’

[John Maindonald]

That is odd. I can do:

> library(XML)
> sessionInfo()
R version 2.15.1 (2012-06-22)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

locale:
[1] en_AU.UTF-8/en_AU.UTF-8/en_AU.UTF-8/C/en_AU.UTF-8/en_AU.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets 
[6] methods   base     

other attached packages:
[1] XML_3.9-4

loaded via a namespace (and not attached):
[1] tools_2.15.1

Also under help(package='XML'), go to the Description file, I see:
  Date/Publication: 2012-01-31 07:37:18
  Built: R 2.15.0; universal-apple-darwin9.8.0; 2012-03-31 00:12:17 UTC; unix
  Archs: i386, ppc, x86_64

I've not compiled it.  But maybe there is a risk that if I try to do anything with
it, it will fail?   Is the difference that I have a 2.15.0 build?

AFAICS XML currently doesn't pass checks on any platform, so there are no binaries and you have to compile it from sources. If you want both 32-bit and 64-bit you'll have to use --merge-multiarch INSTALL option or use the two-step process described in the Mac FAQ.
