Hi All,

I'm having real hassles with port - most packages fail to install, with a segfault, e.g.:

At other times, I get a bus error but I didn't save a copy/paste of that, and it's not reproducible.

I've tried using a different tclsh, but the same problem persists. I'm not certain whether port is using the new one... I've exported PATH=/usr/local/bin, and which tclsh points to the newly installed ActiveState tclsh, but I don't know if port uses its own internal version or something?

Any suggestions on where to start debugging this?

So far I've tried uninstalling and reinstalling, selfupgrade, moving fink (/sw) out of the way in case it was causing a conflict, but with no luck. I get this problem on almost all packages. Interestingly, it was not there originally - at least, there are some packages which I had installed before I removed and reinstalled port, which now fail to install.

Thanks for any help, dave

did you do all the folowing when removing macports? MacPorts can be removed by issuing the following command from within Terminal: sudo rm -rf \ /opt/local \ /Applications/MacPorts \ /Library/Tcl/macports1.0 \ /Library/LaunchDaemons/org.macports.* \ /Library/StartupItems/DarwinPortsStartup On a previous occasion, I had failed to remove the LaunchDeaemons and Tcl items and got problems. and btw you know your PATH has to include /opt/local/bin and /opt/ local/sbin do you not? good luck!

That should not happen (obviously). Never seen this problem before.

Make sure you have the latest OS and all updates (10.4.10 or 10.3.9). Make sure you have the latest Xcode (2.4.1 for 10.4.10; 1.5 for 10.3.9). Make sure you have the latest MacPorts (1.5.2). Make sure you do NOT have anything at all installed in /sw, /usr/local or any other place referenced in your PATH. Just have MacPorts, which is usually in /opt/local. It works great by itself, but other software installed in other locations can cause unpredictable problems.
