By verifying what your "md5sum" says with what has has been published,
e.g. on the website or or Freshmeat.net. The text there says:

  Released the first production version. <P><B>Md5sum:</B><BR>
  bba45febd501acf8e19db402506dae94 gnupg-1.0.0.tar.gz

So the out output of "md5sum gnupg-1.0.0.tar.gz" should give you an
indication if the tar.gz that you downloaded is identical to the 
tar.gz the poster of the above lines md5summed.
