It's a bit difficult to comment about what sort of quasirandom event may have affected the integrity of your device, but here is a theory based on my experience: If you updated from binaries (32 bit) that were on the Bioconductor server, then you may have overwritten your compiled source 64 bit versions. It is rather easy to do that without noticing if you are using the GUI Installer. (The fix is also very easy.)

And MacOS X 10.5.6

Last Nov I ran some 64bit stuff, no problem, and have not installed removed
any R or BioC stuff since then

Now I need to rerun and for several packages I get

package 'xxx' is not installed for 'arch=x86_64'

So I do

source ("http://www.bioconductor.org/biocLite.R";)
biocLite (c("xxx", "yyy", "zzz"), type="source")
And reload them

And then things work

My question: where how why did my 64bit stuff go?

Thank you
