Install fails for gcc42 - libgfortran.a has no symbols?!

[Randy Burgess]

Having switched to Snow Leopard (10.6.1) for my white Macbook (Intel  
Core 2 Duo) I belatedly realized I needed to reinstall Macports. I've  
followed the migration instructions, i.e. installing the latest  
version of XCode (3.2, 1610) and of Macports (1.8.0), then cleaning  
removing old ports and re-installing ports I want to keep.

My only problem so far has been trying to reinstall pdftk, which has a  
dependency of gcc42. Here's the error I keep getting for gcc42 - any  
help appreciated:
