I get:

...
make  check-TESTS check-local
make[3]: ingresso nella directory "/home/catonano/projects/guix"
make[4]: ingresso nella directory "/home/catonano/projects/guix"
make[4]: ***  Nessuna regola per generare l'obiettivo "tests/databases.scm", necessario per "tests/databases.log".  Arresto.
...

that translates to
 

"No rule for generating the "target tests/databases.scm" reqired by "testsdatabases.log"

What am I doing wrong ?

Thanks
