we have a RedHat 
  7.2 system and we are trying to apply the distcache_geoff.patch to enable distcache 1.4.5 with 
  stunnel-4.04.  We have run into a snag after the configure script is run 
  and we attempt the "make", it complains that configure.in is missing.  In 
  step 2 is our "configure" line wrong?
   
  # 
  make
  output: 
          cd . 
  && aclocal
        cd . 
  && automake --gnu --include-deps 
  Makefile
        cd . 
  \
                
  && CONFIG_FILES=Makefile CONFIG_HEADERS= /bin/sh 
  ./config.status
        config.status: 
  creating Makefile
        cd . 
  && autoconf
        autoconf: 
  configure.in: No such file or 
  directory
        make: *** [configure] 
  Error 1
   
  Our work around is 
  to change directory into the /usr/src/stunnel-4.04/src and run "make" from 
  that directory to create our stunnel binary.  Any idea why it won't work 
  from the top directory.
   
   
  our stunnel source 
  resides in /usr/src/stunnel-4.04, distcache_geoff.patch is in /usr/src and 
  distcache-1.4.5 is in /usr/local/distcache-1.4.5.  Our installation steps 
  are below:
   
  step 1. 
              
  # patch -p0 < distcache_geoff.patch
   
  output:  
              
  patching file 
  stunnel-4.04/configure.ac
            
  patching file 
  stunnel-4.04/src/common.h
            
  patching file 
  stunnel-4.04/src/options.c
            
  patching file 
  stunnel-4.04/src/prototypes.h
            
  patching file stunnel-4.04/src/ssl.c
  step 2. 
              
  # cd stunnel-4.04
              
  # export CFLAGS="-DHAVE_DISTCACHE_DC_CLIENT_H 
  -I/usr/local/distcache-1.4.5/include"; export 
  LDFLAGS="-L/usr/local/distcache-1.4.5/lib -ldistcache -lnal"; ./configure 
  --prefix=/usr/local/stunnel-4.04 --with-ssl=/usr/local/openssl-0.9.7e 
  --with-tcp-wrappers --disable-shared
