Sorry, I did not know that some OSes could not have the `python2` symlink, I just watched if there was on the Makefile.

Concerning this, we should do a proper configure script. Do you think that's worth it, E`ric?  
Real configure scripts are generally much more complicated than this, since they may deal with systems where $PATH is not delimited by colons; or systems where executable programs may have optional extensions like .EXE; or $PATH variables that have the current working directory included in them as an empty string; etc.
