That shouldn't be necessary - the automake/autoconf programs are only  
used to create the configure script (if you are using the CVS  
version, or if you edit some of the Makefile.am). Once a distribution  
is created, "configure" is just a (very long) portable bourne shell  

However, configure checks to see if "automake/autoconf" has to be  
rerun, and if the clock on your system and/or NFS is seriously off it  
see a Makefile.am that is newer than the "configure" script. The  
easiest solution in that case is to fix the clock and then unpack the  
source again.
