What the problem is and what you should do are two different things. Having just noted the problem above I do not know what you should do about it because I do not know your situation. Is this your personal desktop? Or is this a shared use machine at a univerisity? Or is this a server machine? So many possibilities. Since you do not know about unix file permissions I will assume that you are on a shared use machine administered by someone else. In which case you should ask your system administrator to help you with this software installation. You should always be able to install in your own personal home directory. make prefix=$HOME install Which will work for m4 but fail on packages which configure in the paths. In which case you would need something like this. ./configure --prefix=$HOME make make install Then to make use of this out of your home directory you would need to ensure that PATH contains your $HOME/bin and the same for MANPATH containing $HOME/man and you may need to use 'info --dir $HOME/info' to read the documentation (or set INFOPATH).
