pgindent fails with perl 5.40

I get this error when running pgindent with perl 5.40:

    Attempt to call undefined import method with arguments ("devnull") via package "File::Spec" (Perhaps you forgot to
loadthe package?) at src/tools/pgindent/pgindent line 10.
 
    BEGIN failed--compilation aborted at src/tools/pgindent/pgindent line 10.

It definitely worked with perl 5.38 before.  Not sure if something's
wrong on my side.  Is anybody else already using 5.40?  For the moment,
I just changed the File::Spec import to make it work:

diff --git a/src/tools/pgindent/pgindent b/src/tools/pgindent/pgindent
