Just for your information:

$ md5sum libev-4.15.tar.gz_seamonkey
bd3fe50a18a86f977f91cfc46783f52d  libev-4.15.tar.gz_seamonkey

$ md5sum libev-4.15.tar.gz_wget
3a73f247e790e2590c01f3492136ed31  libev-4.15.tar.gz_wget

$ tar -xf libev-4.15.tar.gz_seamonkey
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

$ bsdtar -xf libev-4.15.tar.gz_seamonkey

$ tar -xf libev-4.15.tar.gz_wget

$ bsdtar -xf libev-4.15.tar.gz_wget

Probably not the concern of SBo, but if the source of libev is 
downloaded using web browser, e.g. SeaMonkey, it cannot be extracted 
using tar.

As can be seen from the commands output above:
- MD5 sums are different, depending if the source was downloaded using 
web browser or wget,
- tar is not able to extract the source downloaded using SeaMonkey, but 
is able to extract source downloaded by wget,
- bsdtar can extract source downloaded using SeaMonkey and wget.

If using links, the MD5 is the same as for wget.

The moral is, don't use GUI tools ;)
