[Slackbuilds-users] Problems with libev source

[Daniel Prosser]

Thank you for the information. I have forwarded this discussion on to
the libev developer along with your explanation of the problem. I will
leave it up to him to decide whether he wants to make any changes on his
end or just write it off as a wget problem (I would probably do that
latter, based on your explanation).
