Unable to build example for CUDA NVlabs SASSI tool - makefile

Question

I am attempting to build and run the example code from the NVlabs project SASSI which can be used to instrument CUDA code. However, I am struggling to get even the included sample Makefile and matrixMul.cu to build and run properly.
I have tried adding the --maxrregcount=16 and -rcd=true nvcc flags, but I think my real issue is with linking properly to the SASSI libraries. All of the library paths listed in the nvcc output below resolve to actual directories with .so files.
Any tips or debugging steps are much appreciated.
$ make clean
rm -f -f matrixMul *.o
$ make branch
/usr/local/sassi7//bin/nvcc -I./inc -c -gencode
arch=compute_35,code=sm_35 -gencode arch=compute_50,code=sm_50
-Xlinker "--wrap=main" -Xlinker "--wrap=exit" -lineinfo -Xptxas --sassi-inst-before="cond-branches" -Xptxas --sassi-before-args="cond-branch-info" -g -O3 -dc -o matrixMul.o matrixMul.cu

* - It MUST BE compiled using only 16 registers!! To accomplish this
* simply compile your library with the nvcc flag, --maxrregcount=16
* - It must define the following functions:
* device void sassi_before_handler(SASSIBeforeParams*,SASSICondBranchParams*)

The solution was to install Boost, set the appropriate paths in instlibs/env.mk and run make all from instlibs/ before trying to build the example code. The paths were set correctly, but not all of the required SASSI libraries had been generated.
