So I have two nlme-versions: 3.1-122 in my R-installation folder, and 3.1-124 in my Documents folder.

It's a user-issue.  You need to tell R to use your user folder as a 
library upon startup.  Since installing and checking of packages is done 
in a separate R process, you would do this by setting an environment 
variable.
