Error building libglademm on Mac OS X 10.4 (Modified by Michael Ekstrand)

I'm trying to build libglademm on Mac OS X 10.4 using my Fink install 
of the gtkmm-2.4 and libglade2 packages.  The libglademm make fails 
with the following error:

g++ -g -O2 -o .libs/basic basic.o -Wl,-bind_at_load

I have examined /sw/lib/libgtkmm-2.4.dylib with nm, and all three 
typeinfos in the error above do appear.

Any help in resolving this would be appreciated.
