[Agda] lost in modules

[Michel Levy]

This morning, I have loaded (from GitHub) the standard library with the version 1.3.
I have change .agda/libraries to the new version. That is my .agda/libraries file :

/home/michel/Agda/PLFA-LIB/plfa.agda-lib
/home/michel/agda-stdlib-1.3/standard-library.agda-lib

But when I retry to load a file "relationsPLFA.agda", agda, on a command "open import Data.nat" is also searching (twice) in the old
version of the standard libray and give the error :

Ambiguous module name. The module name Data.Nat could refer to any
of the following files:
  /home/michel/agda-stdlib-1.3/src/Data/Nat.agda
  /usr/share/agda-stdlib/Data/Nat.agda
  /usr/share/agda-stdlib/Data/Nat.agda
when scope checking the declaration
  open import Data.Nat using (ℕ; zero; suc; _+_)

What should I do to avoid this search in the old library ?
