If I don't use sudo I get this:

Jon-Kalbs-MacBook-Pro:lib jonkalb$ ./buildit
+ for FILE in '../src/*.cpp'
+ clang++ -c -g -Os -arch i386 -arch x86_64 -std=c++0x -U__STRICT_ANSI__
-nostdinc++ -I../include ../src/algorithm.cpp
/usr/bin/lipo: can't create output file: algorithm.o (Permission denied)
clang: error: unable to remove file: algorithm.o: can't destroy file:
Permission denied
clang: error: lipo command failed with exit code 1 (use -v to see
invocation)
