Why gcc-4.2? The default on Lion is llvm-gcc-4.2. Why does libtool think your system library is malformed? These two facts suggest you're trying to use a version of Xcode designed for Snow Leopard. What version of Xcode do you have installed? Ensure it's one designed for Lion. You can get the correct version of Xcode for Lion for free on the Mac App Store.

[JN]: I was going to run

sudo port -d selfupdate && sudo port upgrade outdated

after upgrade to Lion and after Xcode upgrade. I followed URL to latest version of Xcode ​http://developer.apple.com/technology/xcode.html from ​http://guide.macports.org/#installing.xcode and installed Xcode 3.2.2 I didn't noticed, that there is also 4.1 version.

Thank you for your comment. I'm downloading 4.1 and will confirm result ASAP

[ryandesign (Ryan Carsten Schmidt)]

Xcode 3.2.x is for Snow Leopard. Xcode 4.1+ is for Lion.

[jiri@…]

Shall I create ticket for ​http://guide.macports.org/#installing.xcode to be updated?

[jiri@…]

I installed Xcode 4.1, but still can't compile python26

I moved previous Developer-old o trash

What I have to do to use new Xcode 4.1?

I see

gcc
i686-apple-darwin11-llvm-gcc-4.2: no input files

The guide has now been updated.

Clean and try again?

sudu port clean python26

Yes, that's the step I needed. Thank you very much. Solved
