dub commands do not run correctly.

[Alain De Vos]

In order to run commands correctly I have to put soft links :
I.e.
dfmt -> /home/x/.dub/packages/dfmt-0.13.4/dfmt/bin/dfmt
or,
dscanner -> 
/home/x/.dub/packages/dscanner-0.11.0/dscanner/bin/dscanner
Then ./dfmt or ./dscanner run fine.
I use freebsd as O.S.
But "dub run dscanner" or "dub run dfmt" do not give the right 
result.
Did I miss something ?
