unusual warning when linking with boost--ipo looking for dylib in nonexistent directory

I am compiling a C++ program under Mac OS 10.9.4 using icpc 14.0.1 (student version). I use several libraries I have built using icpc to avoid problems I have had when they were compiled with g++. During linking I get the following warning:

$ mpic++ -o dynamix-ga obj/initializer.o obj/main.o obj/mutator.o obj/objective.o obj/output.o obj/parser.o -ldynamix -lga-mpi -lsundials_cvode -lsundials_nvecserial -lboost_mpi -lboost_serialization -mkl -fopenmp
ipo: warning #11012: unable to find /Volumes/bpart/users/mstester/nightly/makebuild1/20131011_000000/dev/build_objs/efi2mac_d0p0flexlm/lib/libirng.dylib

My program runs correctly as far as I can tell, but I am wondering where this warning comes from--that path is not one I have on my computer, and it looks like one left over from building and testing the Intel installer package.

I have only noticed this warning since I started using boost.

Here are the outputs showing relevant environment variables:

$ echo $CXXFLAGS
 -O0 -Wall -std=c++11 -fopenmp -xHOST -no-prec-div -mkl -no-multibyte-chars
