Hello, The m4 utility is not on your system path; you can validate this by trying to run 'm4' from the command line: $ m4 I suspect it will tell you that it cannot find m4. You say that you installed m4 into '/usr/loca/m4'. Did you mean '/usr/local/m4'? Typically, one would install the m4 utility into `/usr/local/bin`, which is on the system path. You will need to adjust your system path to reflect the location of the m4 program (by adding perhaps /usr/local/m4,h or /usr/local/m4/bin, or /usr/loca/m4; whichever is correct). Alternatively, you could re-install m4 into `/usr/local/bin`, which is on the system path by default.
