There's more than one potential pitfall here.  The configure script 
expects that "/projects/intranet" to be the directory containing the
library.  It looks for something like ../include/openssl to see if it can 
find the matching headers there.  Since it failed the header check, it's 
not finding the right ssl.h file (I ran into a similar problem last week 
starting to check on a gnutls configuration).

As TG pointed out, this is saying the ssl library is 64-bits.
Sun's compiler uses -xarch=v9 (in $CFLAGS) to create 64-bit objects.

Rather than setting $CFLAGS, I generally just make a wrapper-script for 
the compiler options, e.g.,

This is "cc-solaris64":

#!/bin/sh
cc -Xa -xtransition -xarch=v9 $*

then I just have to set $CC to "cc-solaris64" (which is easier to remember
than the compiler options).
