As a general rule, if you use a fixed-width font for labels and other widgets, it will be easier to get things to line up nicely. If you must use proportional fonts, you either have to accept some limitations on alignment, or else you have to do a lot more work to enforce the alignment you want.

Update: What I mean is: Perl/Tk does not really truncate or reduce consecutive spaces in the text of a label widget, but when using a proportional font, the spaces are narrower than most characters, whereas with a fixed-width font, such as "courier", every space counts for the same width as any other character, so labels with text strings like the following will come out the same width when displayed with a courier font: 

"one    two"
"three four"
