[R] .libPaths(new) stopped working in 2.10

[Alexy Khrabrov]

I have the .libPaths() defined in my .Rprofile, and it stopped having any effect.  Even if I try to do it in the REPL, as:

> x <- paste(Sys.getenv("HOME"),"/Library/R/",paste(R.version$major,as.integer(R.version$minor),sep='.'),"/library",sep='')
> x
[1] "/Users/alexyk/Library/R/2.10/library"
> .libPaths(x)
> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

Nothing GUI'sh.
(Changing back to r-help as it's by no means obvious yet it's a Mac-only problem.)
Cheers,
Alexy
