Networking :: bash: apt-get: command not found

I am willing to switched from Kubutu to DSL.

However I required my internet to work, which I have to install drivers for seperetly...

I go to ./configure and then:

checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check

So assume I need to build essential then get:
lib/cpp" fails sanity check
bash: apt-get: command not found

What is going on? I urgently need to resolve this if I am to switch as DSL is perfect!
