Instead of polluting the clean Solaris installs, we use user supported
packages not in the "right" places.  Although it makes using autoconf a pain,
it is a nice way to provide packages publically.

Actually, it seems like PLIB builds under Solaris even when that line is
commented out.  Sorry for the confusion - feel free to remove it.
