How to rebuild MOL

[Henry A. Leinhos]

I've  been trying to rebuild the mol-kmods-0.9.71-0.ydl.4.src.rpm (which 
includes the alloc_h.patch) for a 2.6.10 kernel (from ppckernel.org) and 
can't seem to get the sheep driver to compile.  Kernel source is in 
/usr/src/linux, but the /usr/include/linux and /usr/src/asm directories 
are the installed YDL4 directories. The YDL4.0.1 MOL for MacOS 9 seems 
to stall after the network init stuff.

molstart --test gives:

but startmol gives:
-----> Can't open /dev/sheep_net, please check module is present !
Failed to initialize the sheep-<eth0> device
DHCP nameserver exported: 206.15.168.70

    broadcast: 192.168.40.255  nameserver: 192.168.40.1
 

which is where it hangs until (after a *long* while) I get the message:

Failed to initialize the sheep-</etc/mol> device
SIOCGIFFLAGS: No such device


So, I try to rebuild mol-kmods with  CONFIG_SHEEP enabled in the config 
file, which gets me the following messages during the build:

 Building modules, stage 2.

There was another patch (sheep.patch), but that was supposed to be 
necessary only if I changed the system includes to the new kernel source 
(which I don't beleive I have).  Is there anything else I'm missing here?
