did something stupid - removed gzip

[Jason N. Price]

Okay, I just did something that, in hindsight, was very stupid.  :)  I have 
been getting a lot of errors from gzip, so I decided to apt-get remove it 
and then re-install it.  I removed it, but I now seem unable to reinstall 
it because gzip is not there.  Ooops.  Is there any way I can fix this?
