fd-import version error

[adayim]

Hi,

I followed the document here, I got an error after I run the following line of code:

make mk_venv P=../fd_venv

ERROR: Could not find a version that satisfies the requirement fd-import (unavailable) (from versions: none)
ERROR: No matching distribution found for fd-import (unavailable)

And there are some other warnings

WARNING: Generating metadata for package fd_import produced metadata for project name unknown. Fix your #egg=fd_import fragments.
Discarding git+git://github.com/freedict/tools.git#egg=fd_import&subdirectory=importers: Requested unknown from git+git://github.com/freedict/tools.git#egg=fd_import&subdirectory=importers (from -r requirements.txt (line 2)) has inconsistent name: filename has 'fd-import', but metadata has 'unknown'

Can you help me with this? Many thanks.
