[dune-fem] Dune fem 1.4 error DUNE_TEST_2.3.0_VERSION

[Agnese, Marco]

Hello, 
I have compiled the new dune-fem 1.4 with the dune modules 2.3 without any problem (except a warning for the absence of dune-alugrid). After that I created a new project (dune-test-2.3.0) and I try to compile only this module with the same option files that I used to compile dune-fem. I received the following error:

--- going to build dune-test-2.3.0  ---
--- calling all for dune-test-2.3.0 ---
--- calling vcsetup for dune-test-2.3.0 ---
--- calling autogen for dune-test-2.3.0 ---
WARNING: could not find module dune-alugrid,
       module is also unknown to pkg-config.
       Maybe you need to adjust PKG_CONFIG_PATH!
       dune-alugrid is suggested by dune-fem

I do not know what is it and how to fix it. 
Thank you very much,
