[gentoo-user] why multiple versions of java-config, automake, and autoconf?

[Denis <denis.che@gmail.com>]

Hi all...

This is the output of "emerge --info" for the Gentoo box that I'm
still configuring - fresh install.  I configured and compiled a
working version of the kernel, configured CFLAGS and USE flags, etc.
I also ran "emerge -eD system" and "emerge -eD world" and updated /etc
configs accordingly.

Now...  Why are there multiple versions of java-config, autoconf, and
automake shown on my system?  There could be other multi-version
packages...  Is this normal for portage that is configured to
autoclean?  If so, I find it rather interesting that packages would
depend on so many different versions of automake, for instance!
