[SWLUG] conexant usb modem installation

[Pete Prior]

It sounds like it's trying to compile a kernel module for your system.  To
do this you need to not only have the linux kernel installed, but also the
linux kernel headers.  These are usually called something like
linux-headers or linux-headers-generic (on ubuntu and debian anyway).

Try installing the linux headers with:

sudo apt-get install linux-headers-generic

and try again.  You'll probably need some other stuff so it might be worth
doing a:

sudo apt-get install build-essential 

as well to get a basic build environment installed.
