It is thus a yes/no case, where either you can use the compatibility mode if you are not using the unsupported modules, or you have to adjust your code.

I'm not sure I understood it completely, but googling the error led me to a very simple solution that allows the build to complete (hopefully without introducing any regressions). A patch file and modified Portfile are attached to this message.

Thanks. I submitted a ticket for this problem for you:

https://trac.macports.org/ticket/42969

I generated a unified diff of your Portfile changes, removing the lines you had commented out, and also converted your contextual diff to a unified one.

I can confirm that this now builds on Mavericks. However, I am not a C++ developer so I cannot say whether the change you have made is correct. How did you come to this solution? Have you contacted the developers of eigen about whether this change is correct?
