 In mavericks I asked for `shogun +python7` and got:

 This is similar to what triggered #34990, but there the discussion ended
 up veering to a build problem, while here it is a configure problem.

 I looked into shogun's configure script and the function doing the check
 is:
 {{{
 assert_version() {
         name=$1
         mode=$2
         is_ver=$3
         wanted_ver=$4
         is=(`echo $is_ver| sed 's/\./ /g'`)
         wanted=(`echo $wanted_ver | sed 's/\./ /g'`)

         if test -z "$is"; then
                 die "$name did not return version information"
         fi

         i=0

         while test $i -lt ${#is[*]} 2>/dev/null && test $i -lt
 ${#wanted[*]} 2>/dev/null ; do
                 if test ${is[i]} -lt ${wanted[i]}; then
                         if test "$mode" = yes; then
                                 die "$name is outdated: version
 $wanted_ver required got version $is_ver."
                         fi

                         if test "$mode" = auto; then
                                 echores "`echo $is_ver` ... too old
 version $wanted_ver or later required"
                                 return 1
                         fi

                         return 1
                 fi

                 if test ${is[i]} -lt ${wanted[i]}; then
                         return 0
                 fi
                 let i++
         done

         return 0
 }
 }}}

 So, is it just me or this function will croak if '''any''' of the version
 fields is smaller? I.e., in this case 3.0.0 will fail against 2.0.4
 because 0 < 4...

 Bump to shogun devs?
