[galaxy-dev] Proftpd Problem

Hi, I'am trying to set up ProFTP on Debain to enable FTP upload on Galaxy installed locally? I followed the instructions on this link ( http://wiki.g2.bx.psu.edu/Admin/Config/Upload%20via%20FTP) but it doesn't work. When I restart proftpd i get this message : mod_tls_memcache/0.1: notice: unable to register 'memcache' SSL session cache: Memcache support not enabled Thanks, Amine
