I tried using the tutorial
http://wiki.geda-project.org/geda:gsch2pcb_tutorial

but I can't get gsch2pcb to generate a pcb file ( I get "No elements to add
so not creating board.new.pcb")

When I run 'gsch2pcb -v project' I see that my installation on mac doesn't
have the same path to the m4 installation. So I override this in the
project file with:
m4-pcbdir /sw/share/pcb/m4

That doesn't get me past that the PATH to the executable is hardwired. I
note the instructions on how to overload this in the project gafrc file.
The syntax in the verbose output doesn't seem to have any impact on finding
my m4 processor (and doesn't work if you specify it as directed
using gafrc  ERROR: Unable to parse config from
[/Users/villaume/gaf/myproject1/gafrc]: Unbound variable:
gsch2pcb:pcb-m4-command:


ERROR: The gnetlist log may contain more information.))

A friend said I shouldn't use the m4 macros. But I need a modern tutorial,
or instructions on how to force gsch2pcb to see my m4 processor...

my project file:
schematics one.sch two.sch
output-name board
m4-pcbdir /sw/share/pcb/m4
