[R-SIG-Mac] nlme (or base) problem

[Adelchi Azzalini]

library(nlme) does not load,
this is what I get:

R> library(nlme)
Error in .Call("R_lazyLoadDBfetch", key, file, compressed, hook,  
PACKAGE = "base") :
   C symbol name "R_lazyLoadDBfetch" not in DLL for package "base"

However the probleme could be in the base package.
If I try with the Package Manger, then I get this:

Error in .Call("R_lazyLoadDBfetch", key, file, compressed, hook,  
PACKAGE = "base") :
   C symbol name "R_lazyLoadDBfetch" not in DLL for package "base"
In addition: Warning message:
In FUN("Orthodont"[[1L]], ...) : restarting interrupted promise  
evaluation
starting httpd help server ... done

details about my intallation are below.

Adelchi Azzalini
