RE: fetch hangs, part 2

I've been having the same (or a similar problem).  Fetching the distfile for
a port will hang.  I poked some more at this and found that all the sites
fetch is hanging on successfully negotiate the TCP connection then go dead
without closing the connection.  My workaround has been to edit the Makefile
and remove the offending site from MASTER_SITES or manually fetch from
ftp.freebsd.org.
