live-build error: basename: invalid option -- '-'

[Tabrez Ali <stali@geology.wisc.edu>]

Hello

I am trying to use live-build on a squeeze box as follows:

$ lb config -d wheezy -p --archive-areas "main contrib non-free" 
--packages "libpetsc3.2-dev libparmetis-dev make wget subversion"
$ sudo lb build

However I get the following error
...
...
basename: invalid option -- '-'
Try `basename --help' for more information.
P: Begin unmounting filesystems...


Any ideas as to what's wrong. I also tried the commands on a wheezy box 
but again got the same error.

Thanks in advance.
