hangs when building python26 & python27

[Mark Hattam]

Having just (22nd Aug) port upgraded python26 and python27 I ran into the same hang that I often get when building these ports ... I see in Terminal a "shell command cd" failed with a log file reference, but after that I appear to get a complete OS hang which is only resolved with a power-off/reboot. After restarting, the log is not there, I usually port clean and port upgrade again, and it builds through to completion without apparent problem.

This time I copied the logfile to a usb stick before the machine hung (just).

3.06 GHz Core2Duo iMac, 4 GB RAM, OSX 10.6.8, MacPorts 2.0.1

Below is the main.log for the build
