Please remember to cc the maintainer. It would probably be helpful if you could attach the crash log.

It seems to be a problem with the "--no-user-cfg" option, it did some kind of check over and over again including my users python modules $HOME/Library/Python/2.6/site-packages/ until it finally crashed.

I found a workaround:
When I removed the $HOME/Library/Python directory I managed to complete the build.

It didn't generate a log in /Library/Logs/DiagnosticReports or ~/Library/Logs/DiagnosticReports?

[macports@…]

Crash file from /Library/Logs/DiagnosticReports

[jmr@…]

Can't reproduce with current versions; I have stuff in ~/Library/Python and it builds fine. Note that the command in comment:2 is incorrect as it sets the environment variables before running sudo, which then clears most of the environment.
