The canocial fix is to tell the build to use the classic linker option. 
'Well behaved' builds will respect the following setting in the Portfile

configure.ldflags-append  -Wl,-ld_classic

This has worked for me in a few places, like the root6 port. I did 
actually try it in py-scipy and there it did not work, and nor did a 
handful of other tricks I have to get the build to use a certain linker.

In my experience python based builds are not that well behaved when it 
comes to things like respecting the macports build flags...

At this point I am in the 'wait for Xcode 15.1' camp. Usually the first 
X.1 OS release comes along relatively soon after the initial X.0 
release, so I would anticipate it relatively soon, most likely.
