Hi Nick,

thanks for the fast reply.

1.
How can I save the .gz file on my mac? Is this the correct way how I try it?
Should it work with the code you've sent me? (fp = fopen("/Path/To/Some/Place/Writable/curl-7.29.0.tar.gz", "w");)
I am not in the office at the moment so I can test it tomorrow...

2.
The NSAlert Messages will be shown when i start the the Cocoa Application. So I think this should be correct.

3.
Sorry, this is the standard footer in my mails. Sure are you authorized :-).

Thanks,

Jürgen
