I'm getting the following error.

I've unset my path and then set my path to 
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

where it should pick up all of the GNU gcc, ar, ld, bison and all of the 
other tools prior to any SUN provided tools.

For some reason it seems to want to use Sun's M4, which is baffling 
considering I have m4 available in /usr/local/bin.

[root@hostname /usr/src/cfengine-2.0.5]# which m4
/usr/local/bin/m4

why is it picking up /usr/ccs/bin/m4?  and how do I force it to ignore it?

Thanks,
