But chances are the build is using the default 10.4 ABI.  Adding 
MACOSX_DEPLOYMENT_TARGET=10.6 as an env variable to ./configure may fix 
it.  There is an open issue to change configure to use better defaults 
for this.  (I'm right in the middle of reconfiguring my development 
systems so I can't test it myself immediately but I'll report back 
shortly.)
