Looking more carefully at the error message you posted, note that 
the actual error is coming from File::Temp::_gettemp.

$open_success = sysopen($fh, $path, $flags, 0600);

is returning the error condition. So, the invalid value being passed 
is either in $flags or the umask. I suspect $flags.

On a hunch, could you check what the following script prints:

#!/usr/bin/perl

use strict;
use warnings;

use Fcntl;

my $EXLOCK = eval {
    local $SIG{__DIE__} = sub {};
    local $SIG{__WARN__} = sub {};
    &Fcntl::O_EXLOCK();
};

print "'$EXLOCK'\n";

__END__
