Thanks you very much Vijay,
it works on osx 10.5.2 with glpk-4.23.

Just a remark to make the compil even more easely!

Why not use standard environnement variables with some
reasonable default values to guess where glpk is installed
(with configure --prefix)
(e.g. GLPK_INCLUDE and GLPK_LIB as used in:
   http://theory.stanford.edu/~srirams/Software/lpinv.html

I had to modify the Makefile as following:

GLPKINC = $(GLPK_INCLUDE)
GLPKLIB = $(GLPK_LIB)

# add -L$(GLPKLIB)
cspsol: $(OBJS)
        g++ -o cspsol $(OBJS) -L$(GLPKLIB) -lglpk -lm

Thank you for you contribution!
