I recently installed LAME encoder on my server to convert wav to mp3 and that worked with './configure, make, make install;I then tried to install OGG encoder and that requires './configure, make, sudo make install' - which I cannot do, since I don't have a VPS (and I'd rather not pay $15 a month for a VPN just to install a codec).I'm new to all this, and I understand sudo gives you permissions - but I have been trying to find out why exactly some 'make installs' require sudo access and others dont. I haven't yet found the answer. Again, very knew to this so I'm just trying to learn what's going on. 
Why do some packages use 'make install' while other use 'sudo make install'
software installation;sudo;make
