Yes, I'm interested.
It seems that there is a problem with the login.
I could compile the current cvs source, the server runs, but ...
I cannot login.

$ ftp localhost
Connected to loreley.antigone.familiehaase.de.
220 ProFTPD 1.2.9rc1 Server (ProFTPD Default Installation) [loreley.antigone.familiehaase.de]
Name (localhost:Gerrit): gerrit
331 Password required for gerrit.

530 Login incorrect.
ftp: Login failed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> quit
221 Goodbye.

I applied the following patch to the current source, but it seems
that it is still all wrong...
