Matthew,

this problem turned out to be a real showstopper, and it was only after several 
days that I was finally able to fix it with Jarno's help. Here's what I did to 
get it running under Snow Leopard:

I had to track down the library that was getting confused with the system 
library. In my case, it turned out that the gfortran binary I had installed 
drags around its own libstdc++.dylib in /usr/local/gfortran/lib, the system has 
its own version in /usr/lib, and if you have gcc installed, you'll most likely 
find another one in /usr/local/lib/ if you built from scratch, or some other 
place if you use a packet manager.

In my case, to make sure that the gcc-version is used in favour of any other 
version I think that I simply issued

export LDFLAGS="/usr/local/lib/libstdc++.dylib"

before ./configure, and all was fine ever after.

Good luck,

        Alex
