Failed to parse file lang/rust/Portfile

[Bee]

Whenever I selfupdate MacPorts I get this message:

Failed to parse file lang/rust/Portfile: can't read "stage0(hash)":  
no such element in array

I deleted the whole folder 'rust' and reran:
sudo port -v selfupdate

The 'rust' folder was restored but still receive the failed message.

--and--

port info rust
Error: Port rust not found
