Parsec compillation error

I am following the installation guide for ccx 2.20 in conjunction with Pastix and I get this error while compiling Parsec:
– Looking for COREBLAS - pkgconfig not used
– pkg-config not available. You need to provide COREBLAS_DIR or COREBLAS_PKG_DIR
– Could NOT find COREBLAS (missing: COREBLAS_INCLUDE_DIRS COREBLAS_LIBRARIES COREBLAS_LIBRARY_DIRS)
– A library with COREBLAS API not found. Please specify library location.
COREBLAS_INCLUDE_DIRS =
COREBLAS_LIBRARY_DIRS =
COREBLAS_LIBRARIES =
COREBLAS_LDFLAGS =
CMake Error at dplasma/tools/PrecisionGenerator/CMakeLists.txt:12 (message):
2to3 python utility not found. Use Python 2.7 or provide the 2to3 utility.
I am using the stock make_parsec.sh from src folder. Has anyone encountered this error?
