Milter-greylist

Hello ! 

 I compile well the milter with SOLARIS 9 but I have a problem while
compiling for SOLARIS7

configure
    46  checking for gcc... gcc
    47  checking for C compiler default output file name... a.out
    48  checking whether the C compiler works... yes
    49  checking whether we are cross compiling... no
    50  checking for suffix of executables... 
    51  checking for suffix of object files... o
    52  checking whether we are using the GNU C compiler... yes
    53  checking whether gcc accepts -g... yes
    54  checking for gcc option to accept ANSI C... none needed
    55  checking for flex... flex
    56  checking for yywrap in -lfl... yes
    57  checking lex output file root... configure: error: cannot find
output from flex; giving u

The Flex userd is the folowing:
   pkginfo -il SMCflex
   PKGINST:  SMCflex
      NAME:  flex
  CATEGORY:  application
      ARCH:  sparc
   VERSION:  2.5.33
   BASEDIR:  /usr/local
    VENDOR:  FSF
    PSTAMP:  Steve Christensen
  INSTDATE:  Sep 29 2006 09:22
     EMAIL:  steve@...
    STATUS:  completely installed
     FILES:    108 installed pathnames
                 7 shared pathnames
                13 directories
                 2 executables
              5027 blocks used (approx)

Il use the GNU C 2.9.5

What is the problem ? Where can I find a binary of the greylist-milter
compiled for SOLARIS 7 ? 


 Best Regards
