[stunnel-users] "bind: Address already in use (48)"

Please pardon me if this is an improper question to the list. But I am a freshman who uses stunnel to connect to his university library proxy from abroad. I had stunnel installed and it worked properly, but after an upgrade of all old ports, solicited by the installation process of a new application requiring MacPorts, stunnel doesn't work anymore. I have tried to re-install it, but I still get the same error message

Error binding squidssl to ::1:8095 bind: Address already in use (48)

Any clue as to what might have engaged the 8095 address and on how I might try to solve the problem?

Best, -dino buzzetti
