You're free to install all versions.  Specifically when it comes to
autotools, you generally want to install the very latest that your
distro supports.

But if you do install more than one, you'll notice that /usr/bin/automake
is a symlink to:

[cdfrey@ src]$ ls -l /usr/bin/automake
lrwxrwxrwx 1 root root 26 Sep  4  2007 /usr/bin/automake -> /etc/alternatives/automake

The /etc/alternatives directory is where you can choose which version of
programs you want to use by default:

[cdfrey@ src]$ ls -l /etc/alternatives/automake
lrwxrwxrwx 1 root root 21 Mar 25  2009 /etc/alternatives/automake -> /usr/bin/automake-1.9
