The _expression_

    $path_elem =~ s{(\s)}{\\$1}gio;
    

The /io is not needed/wanted.
Right about the /i. That's conventional laziness on my part, as it is usually what I want, though it would be detrimental in this case.

And I always use /o unless I'm intentionally interpolating in my pattern. Perhaps the regex engine is smart enough these days to infer that from the pattern, but it's another piece of conventional laziness.
I think it's easier to read this:

my $win32 = $^O =~ /Win32/i;
my $path_elem = $ENV{CLEARCASE_PN};
$path_elem =~ s/ /\ /g if not $win32;
Sure. It's a choice. But s/(\s)/\$1/g will handle other whitespace, too.
PS: Top-posting is something we try to avoid in these lists.
Sorry.  Understood.
