Remove the -ar, else if you get a protocol error, this ports loops for ever
with a simple "make fetch", thus it otherwise it prevents a
	"cd /usr/ports ; make -k fetch BATCH=YES"
having any chance of fetching more distfiles - as it loops forever.

Once I removed this damed ar, it passed by my ftp protocol error,
got on to next fetch rule & succeeded, log below:
---------------
ake fetch

=> egenix-mx-base-2.0.6.tar.gz doesn't seem to exist in /usr/ports/distfiles/.
