flex version

[Peter Cheung]

hi

   my flex in mac is installed using macports. 

$flex --version

flex 2.5.35 Apple(flex-31)

And the line in configure fail

version=`$LEX --version | $AWK '{ split($NF,x,"."); print x[1]*10000+x[2]*100+x[3]; }’`

Better to change it to:

version=`$LEX --version | sed 's/flex //'|sed 's/ .*//'| $AWK '{ split($NF,x,"."); print x[1]*10000+x[2]*100+x[3]; }’`

thanks
