If the system does not have current versions, yes. But almost all 
installations I know have more or less current versions of autotools (or at 
least the versions which are needed to build things on this platform. If you 
want to create a "configure" which runs on the newest systems, you naturally 
need to get a version which covers them, e.g. MAC darwin. The maintainer 
producing the official installation tarballs should always use recent 
versions). Autotools is certainly not a beautiful streamlined solution, but 
it is the standard and is used by a wide number of packages. Abstracting all 
kinds of compiler and linker differences is by the nature of things an ugly 
task, and one can only hope that this will improve over time, so that the 
internals of things like autotools need no longer be so complex.

Using autotools needs a bit of learning the syntax for defining build targets, 
but it is very easy. If you tell me what you want to do I'll gladly help you 
to get over the first few steps - it's quite straightforward. There is also 
the online autobook I was referring to in previous mails:

This is my failure. I had it in an earlier version but was dissatisfied with 
the way it was done. Actually I'm still a bit opposed to the fact that a 
generic configure should contain site specific installation directories, but 
I'm just adding it now and I'll check it in with Gerri (the locations can 
always be given via the additional flags, and then you are absolutely sure 
that the correct location is chosen).
