Building against 10.5 SDK, link error on "open"

Subject: Building against 10.5 SDK, link error on "open"

I'm trying to get my project to build against the 10.5 SDK, but when I switch it from $(DEVELOPER_SDK_DIR)/MacOSX10.4u.sdk to 10.5, I get a couple of errors:

Undefined symbols:
  "_open$UNIX2003", referenced from:
      _CreateEventForPath in editorBridge.o
  "_close$UNIX2003", referenced from:
      _SimplePing in SimplePing.o
      _CreateSocketForCommunicationWithHost in SimplePing.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

SimplePing.o is from the Apple provided example. editorBridge is mine, an implementation of kQueue, which uses the "open" found in fcntl.h

I don't know enough about UNIX flavoured C to figure out what settings I might need to change to solve the link error. Suggestions? Thanks!
