xmltooling-1.4  AIX 5.3

I am trying to specify the location of curl when building xmltooling.
I have tried each of the following options to configure:


1. Specify the directory where curl is installed:

     configure --with-curl /usr/local/shibboleth/curl

   But instead of using the path I specify, configure finds an old version 
   of curl that I DON'T want to be used:

     configure:19348: checking for curl-config
     configure:19366: found /usr/local/bin/curl-config
     configure:19378: result: /usr/local/bin/curl-config

   And complains that it is not suitable:

     checking for CURLOPT_SSL_CTX_FUNCTION in curl.h... 
     configure: error: need libcurl that supports CURLOPT_SSL_CTX_FUNCTION


2. Specify the directory where curl-config resides:

     configure --with-curl /usr/local/shibboleth/curl/bin

   Seems to still be looking in /usr/local/bin, but this time can't find
   curl-config there!  (Not that I want it to.)

     checking for curl-config... /usr/local/bin/curl-config
     configure: error: curl-config not found, may need to 
     use --with-curl option

   Ah, but I did use it. And why do you keep looking in other
   locations?


3. Specify the full path to curl-config: 

     configure --with-curl /usr/local/shibboleth/curl/bin/curl-config

   Same result as (1) above; found old version and doesn't like it:

     configure:19348: checking for curl-config
     configure:19366: found /usr/local/bin/curl-config
     configure:19378: result: /usr/local/bin/curl-config

     checking for CURLOPT_SSL_CTX_FUNCTION in curl.h... 
     configure: error: need libcurl that supports CURLOPT_SSL_CTX_FUNCTION


So:

   ** What exactly is the argument to --with-curl supposed to be?

   ** Why does configure look elsewhere for curl even when I
      specify --with curl?  Shouldn't configure abort if my --with-curl
      is not acceptable? (To do otherwise is fraught with peril.)

   ** Why does configure recommend I use --with-curl even when I
      do in fact use --with-curl?

   ** What is the immediate workaround?

It appears that I will have a simlar issue with log4shib-config, 
but I haven't gotten that far yet?
