When running configure under HPUX-10.20, I got this message:

  sed: Function s%@ACLOCAL@%/my/dir/apache/ApacheJServ-1.0/src/scripts/build/unix cannot be parsed.

The problem boiled down to this line (line 839 in my copy of
configure for the 1.3.9 distribution):

  missing_dir=`cd $ac_aux_dir && pwd`

It turns out that under the shell I'm using (zsh, although
the script invokes #!/bin/sh) the "cd" command changes directory
and issues a "pwd" automatically, so the above line essentially
concatenates two copies of a directory name with a newline in
between them.

To fix this, I had to change the line to:

  missing_dir=`cd $ac_aux_dir`

Hope this helps!
