Error installation Minimserver 0.8.3.4

[Skynet]

Sorry i am new in this forum. I Actiliced my DS411j to DSM 6.0 and when I tried to install minimserver 0.8.3.4 gives me an error message is as follows: "the undefined port configured for this package or use another service is reserved for system use. Disable or modify the conflicting service or contact the developer to modify the package configuration"
Is possible help me to install minimserver in my NAS.
Thx
