[gNewSense-users] Removing dev packages

[Stayvoid]

Hi,

According to this guide [1] I should do the following:
sudo apt-get remove gdb gcc gcc-4.4 gcc-4.4-base dpkg-dev libc6-dev
cpp cpp-4.4 g++ make libstdc++6-4.4-dev

But I've got this error:
"You are about to do something potentially harmful."

I don't want to paste the whole output, but there were such packages
like apt, bash, gnupg, ssh, sudo and mount.

How to remove *-dev packages without affecting something important?
