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 load the 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
