ftp on new macs

Thomas,

On my new macbook I have had trouble sending things to CRAN by ftp.  
This  message is intended to provide help for people with similar  
difficulties,  and to see if there are better solutions.

I'm not sure which FTP client you use, but this seems to work just  
fine (and thanks for pointing out the issue!):

curl --disable-epsv -T MYPACKAGE ftp://cran.R-project.org/incoming/

Cheers,
Simon
