Unfortunately this breaks AIX, Solaris, and Tru64 for unknown reasons :(

The error message:

checking whether to enable mod_ssl... no
./configure: syntax error at line 9031: `^' unexpected

Snippet from configure (line 9031 is the first one with '^':

      #
      # shotgun approach: find all occurrences of the openssl program
      #
      ap_ssltk_try=""
      for p in /usr/local/openssl/bin /usr/local/ssl/bin $path; do
        if test -f "$p/openssl"; then
          ap_ssltk_try="$ap_ssltk_try $p"
        fi
      done
      if test "x$ap_ssltk_try" = "x"; then
        { echo "configure: error: 'openssl' not found in path" 1>&2; exit 1; }
      fi
      for p in $ap_ssltk_try; do
        ap_ssltk_version="`$p/openssl version`"
        case "$ap_ssltk_version" in

                break

      done
      if test "x$ap_cv_ssltk" = "x"; then
        { echo "configure: error: requires OpenSSL 0.9.6 or higher" 1>&2; exit 1; }
      fi

This little shell script seems to work fine on Tru64, so I'm doubly confused.

---------cut here-------
ap_ssltk_version=$1
 
case "$ap_ssltk_version" in
            *[^0-9a-z.][1-9]* | \
            *[^0-9a-z.]0.9.[6-9]* | \
            *[^0-9a-z.]0.[1-9][0-9]* )
                echo "we got a match"
                ;;
            *)
                echo "no match"
                # skip because it is too old or a bad result
                ;;
esac

Any suggestions?
