Usually its better to have an empty label already within the GUI 
design then simply set its text attribute....

If you really must create them dynamically you should find an 
unpack() method exists (it certainly does in Tcl/Tk itself!)

Just clear the text attribute of the original Label...

lError = Label(parent,.....)
lError.pack(....)
lError['text'] = "Invalid Entry"  # set it
lError['text'] = ""               # clear it

Why not use a frame? Frames are your friend when using Tk!
Especially with the packer layout manager...
