There is a build failure of ilmbase with Mac OS Lion and Xcode 4.3. Here is the log:

The relevant error in the log seems to be:

:info:build ../libtool: line 8976: /Developer/usr/bin/clang++: No such file or directory

The port copies the libtool port's glibtool into the worksrcpath as libtool, so the problem is that your libtool port was installed back when you were using an earlier version of Xcode. Rebuild libtool, clean ilbmase, try again.

sudo port clean libtool ilmbase
sudo port -n upgrade --force libtool
sudo port install ilmbase

Thank you very much! It works!
