There are about 3 ways to handle it.
1) use 'require' and maybe 'import' instead of use to delay loading.
my $is_GUI = 1;
...
require Tk;
import Tk; # if needed
2) use 5.8 if conditional:
my $is_GUI = 1;
...
use if $is_GUI, 'Tk';
3) use an eval on the use to delay loading:
my $is_GUI = 1;
BEGIN { eval "use Tk" if $is_GUI; }
