SSL Verification on 4.2.0

[Nate Sutton]

In the latest LFTP (4.2.0) ssl:verify-certificate defaults to yes. This was 
surprising as I assumed (incorrectly) that it was on by default in previous 
versions. This doesn't seem to be an issue on the Linux systems we're using, 
and is a net positive IMO, but it fails on OSX 10.6.6. OSX stores the cert 
files in the Keychain application, apparently, so they can't be found on the 
file system. Does anyone know a way to get SSL verification working on OSX 
10.6.6 with LFTP 4.2.0?
