When you say "libraries", are you referring to libXXX.{a,so}, or "The
ABC Corp Widget Library" (a collection of libraries and non-standard

Typically, changes in toolkits that cause huge inconsistencies are given
different major version numbers, but automake will probably be 1.X

Segmenting automake into automake-1.4/1.5/1.6 might be OK so long as
users have the choice of choosing "automake-X.y", or simply choosing
"automake" (which would continue to be the latest automake major
revision).  I for one like to install automake, and know that when my
check for updates yields "nothing new", my automake is the latest.

Did you consider getting the libraries updated?  Yeah, you probably did.

This *is* an automake issue, and not a libtool issue, right?
