you need to use gawk, not mawk or awk .
...ok, so I changed all references of "awk" to gawk (there was no "mawk") in Makefile.common...but get the exact same message...
oki..i had quite a similar error message, and the gawk switch solved it..perhaps an upgrade of the developer tools to something 3.3 based would help, otherwise maybe someone else has some hints...
