Did someone bork eval_variants?

[Jordan K. Hubbard]

I'm seeing this from any port and any operation, so it looks like  
something has gone south in ToT

jkh at sam-> port -d -v livecheck
DEBUG: Changing to port directory: .
Can't map the URL 'file://.' to a port description file ("extra  
characters after close-quote").
Please verify that the directory and portfile syntax are correct.
To use the current port, you must be in a port's directory.
(you might also see this message if a pseudo-port such as
outdated or installed expands to no ports).
