perl5.8 fails to build, reports that /usr/local/libstdc++.6.dylib isn't of the right architecture on Snow Leopard.

[crappiest.name.ever@…]

I am using Snow Leopard 10.6.1, and macports 1.8.1. I have recently upgraded, and decided I did not need all my previous macports software, so I uninstalled it. Soon, though I reinstalled it, along with Apple's dev tools 3.2.1, the latest version, the last time I checked. I tried to install perl5.8 (default variant, and using 32-bit compile), and this is what happens.

Some really ugly output there, sorry about that. Could someone please help, though? That would be greatly appreciated.

The question is, where did /usr/local/libstdc++.6.dylib come from? You should rename your usr/local folder to /usr/local.moved, then clean and try again.

We don't support building when there's *anything* in /usr/local
