There are various methods.  One is this:

if ($^O eq 'MacOS') {
  eval <<EOM;
    use Mac::Files;
    use Mac::Glue ':all';
EOM
  die $@ if $@;
}



If you don't like eval(), you can try:

if ($^O eq 'MacOS') {
  require Mac::Files;
  require Mac::Glue;
  Mac::Files->import;
  Mac::Glue->import(':all');
}


You can also use autouse, which can be cool, depending on how your program
works.

# functions here take prototype
use autouse 'Mac::Files' =>
  qw[FindFolder kOnSystemDisk() kTemporaryFolderType()];

# sigh, we get subroutine redefined errors
local $SIG{__WARN__} = sub {print @_ unless $_[0]=~/Subroutine \w+ redefined/};

if ($^O eq 'MacOS') {
  $tmp = FindFolder(kOnSystemDisk(), kTemporaryFolderType());
}
