MacPorts 2.0.4 and recommendation for Lion Xcode version

[Tabitha McNerney]

Hello Harald and friends,

So far, as I continue to build many MacPorts from 2.0.4 on the Mac (a
64-bit machine) with Lion 10.7.3 and Xcode 4.3.1, its going quite well
(besides the questions I had asked previously). The only thing I noticed
(but this doesn't seem to be new as I'm pretty sure I saw this on a
different Mac) is that I sometimes get "conftest" crashes that get logged
in /Library/Logs/DiagnosticReports, which I'm fairly certain happens during
a process associated with MacPorts (though I could be wrong). For example
here's part of one:

Process:         conftest [87339]

Has anyone seen these types of crashes show up in their system?

Thank you,
