[R-SIG-Mac] Problems installing pakages with R.app

[Romuald Riem]

Dear all,

I'm using R.app (v1.01 and 1.02 pre build 944) on OS X.3.7.

I can't uppgrade sources packages with the GUI because I've messages like
this:

ERROR: failed to lock directory
'/Library/Frameworks/R.framework/Versions/2.0.1/Resources/library' for
modifying
Try removing 
'/Library/Frameworks/R.framework/Versions/2.0.1/Resources/library/00LOCK'


When I use R in the terminal (with sudo), I haven't this problem. I've just
notice this warnings:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LC_ALL = (unset),
        LANG = "fr"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Do you know what's happend and how I can fix it ?


Thanks in advances
