Check out this link: http://fstanley.github.com/blog/2012/06/10/fixing-ghunit-sentestcase-link-errors/
Basically you need to add:
$(SDKROOT)/Developer/Library/Frameworks
and
$(DEVELOPER_LIBRARY_DIR)/Frameworks
to the framework search paths in the settings for your test target.
I had the same error and this fixed it.
Note: that the items must be added in that exact order, per http://forum.sparrow-framework.org/topic/cant-run-unit-tests.
