I was answering when Ralf's answer came though, so I thought I'd comment
on his solution (which was pretty close to mine anyway). While this
method works, it does have it's problems.
First of all, you need to know how many levels to expand as you're
writing the code in configure.ac.
Second, you should consider that you're being more accurate when you
tell the user they're installing into ${datarootdir}/blammo. The reason
is that the user still has the option of changing the value of
${datarootdir} on the make install command line, which would override
the hard-coded path you want to display from configure:
$ make datarootdir=/usr/share install
Perhaps a better message would be:
configure: WARNING:
The modules will be installed by default in /usr/local/share/blammo
(${datarootdir}/blammo).

John
