<posted & mailed>

Here is what i have installed:

     mgetty-fax
     sl-modem-daemon
     sl-modem-source
     
     cd /usr/src
     sudo tar xfj sl-modem.tar.bz2
     cd modules/sl-modem
     sudo module-assistant auto-install sl-modem-source
   
I get:  'installation failed'

Looking into /var/cache/modass:
 (...)
  make[4]: Entering directory `/usr/src/linux-headers-2.6.17-11-generic'
