Need help with martian_modem install

[jakev383]

I have an old laptop that I'm setting up as an email station for my grandparents.  I've installed my copy of 5.8 SOHO on it, and have everything pretty much working as needed.
The laptop has a Agere 56K Winmodem in it, and I ran scanModem to identify the modem.  I downloaded martian_modem (martian-full-20080407) but when I try and compile it, I get this error:

Code:

root:# make all
make -C kmodule/ modules
make[1]: Entering directory `/home/vick/martian-full-20080407/kmodule'
make -C /lib/modules/2.6.20.3/build M="/home/vick/martian-full-20080407/kmodule"  modules
make: Entering an unknown directory
make: *** /lib/modules/2.6.20.3/build: No such file or directory.  Stop.
make: Leaving an unknown directory
make[1]: *** [modules] Error 2
make[1]: Leaving directory `/home/vick/martian-full-20080407/kmodule'
make: *** [all] Error 2

I think I have the correct (and correctly) installed kernel source, headers, and modules source. 
What am I missing, or is there an easier way to do this?

For those that are interested, I'm setting the laptop up to dial up to an Internet connection and grab their email at 3am, then disconnect.  It will also grab pictures from a remote dir, rsync'ing them locally, to use for the screensaver slideshow which should be trivial. 
Thanks!

it doesnt look like you have the symlink it wants

/lib/modules/2.6.20.3/build: No such file or directory.  Stop

/lib/modules/2.6.20.3/build should be a symlink to /usr/src/linux-2.6.20.3

Hmm. The link existed.
I removed it, then created a symlink and it compiled a little further.  Now I get this error, which I'm guessing needs a "compat" package:

Code:

make -C kmodule/ modules
make[1]: Entering directory `/home/vick/martian-full-20080407/kmodule'

Thanks for the tip!

it doesnt look like you have the correct kernel source for your running kernel.
