bzip2: bunzip2 already exists and does not belong to a registered port

[hamradioactive@…]

I'm very new at this.

Computer: Mac Mini 2.26 GHz Intel Core 2 Duo
Software: Mac OS X Lion 10.7.4 (11E53)

MacPorts-2.1.2-10.7-Lion
Xcode Version 4.4.1 (4F1003)

I then tried to run sudo port install gnuradio as shown on: ​http://www.oz9aec.net/index.php/gnu-radio/gnu-radio-blog/373-gnu-radio-330-on-mac-os-x

It starts to run ok, and starts the build then it stops with

Error: Processing of port gnuradio failed

Hamradioactive$ sudo port install gnuradio

I then did

Hamradioactive$ port -f activate bzip2
Error: Insufficient privileges to write to MacPorts install prefix.

Well I'm at a loss. Can anyone help? I've included the bzip2 log

Remember to use WikiFormatting when writing in Trac.

As the error message says, the problem is that MacPorts (via the bzip2 port) wants to install the file /opt/local/bin/bunzip2, but that file already exists and MacPorts does not think it put it there. That's a problem. Where did that file come from? If you cannot answer that question, then who's to say there aren't other files around that would conflict with other MacPorts ports? In that case the best course of action would be to follow the ​uninstallation procedure. That will ensure that all files in /opt/local are gone. Then you can reinstall MacPorts and whatever ports you want, knowing that there are no foreign files present that might interfere.
