R help - Dec 2009 - .libPaths(new) stopped working in 2.10

I used to have the following in my .Rprofile:

if (length(.libPaths())==1)
.libPaths(paste(Sys.getenv("HOME"),"/Library/R/",paste(R.version$major,as.integer(R.version$minor),sep='.'),"/library",sep=''))

-- and it added my user-defined library directory.  Then I installed
packages there, so during an upgrade, I'd know exactly which packages
I installed and auto-upgrade with a script.

However, in R 2.10's Mac OSX GUI, .libPaths(new) does nothing...  Did
its behavior change?

Cheers,
Alexy

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

It works fine for me, both from the GUI and from the command line  
startup:

 > .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"
 > .libPaths(new="/Users/rturner/Rlib")
 > .libPaths()
[1] "/Users/rturner/Rlib"
[2] "/Library/Frameworks/R.framework/Resources/library"
