readline() on closed filehandle $fh at installman line 115.

I am not sure if the installation was successful or not, the last line output readline() on closed filehandle $fh at installman line 115 could be a warning or an error.

Thanks for the report. I guess it's just a harmless warning, but I haven't checked yet.
