Ok, I ran the command as you said.
philippe:$ ls -la /lib/modules/22.214.171.124/build
lrwxrwxrwx 1 root root 23 2007-07-22 09:49 /lib/modules/126.96.36.199/build -> /usr/src/linux-188.8.131.52
Then, to make sure, I ran slapt-get.
root:# slapt-get --install kernel-src

kernel-src is up to date.

I guess they warned us about using other kernels. But I'd still like to be able to compile stuff for the 184.108.40.206. It's a hobby of mine to learn how get myself out of problems.
