xorg-libxcb @1.7_0+python26 Nested evaluations (infinite loop?)

[kurt.heumiller@…]

Running SnowLeopard, upgraded XCode and reinstalled latest version of MacPorts, was trying to follow the migration suggestions but cannot get past uninstalling

bmdva:~ kh65$ sudo port -fp uninstall --follow-dependents installed

... and it goes on like that until I ctrl+z

Perhaps the problem is line 10 of the log file:

:debug:uninstall Logging disabled, error opening log file: can't read "portpath": no such variable

What does this mean?

In the meantime, this is the workaround I used

port installed > myports.txt
cat myports.txt | xargs sudo port -fp uninstall

The workaround described above by macporter90210@… works perfectly. Thank you very much!

port installed > myports.txt
cat myports.txt | xargs sudo port -fp uninstall

Which is exactly equivalent to sudo port -fp uninstall installed; i.e. the only difference is not using --follow-dependents. Maybe there was a dependency loop in your registry?

Since 2.0.2, ports will be uninstalled in dependency order anyway, so I've removed --follow-dependents from the instructions. That's probably all that can be done without a reproducible test case.
