Configure can't find SSL library

[WilliamOMS]

Hello,

I'm installing Nginx 0.8.40 on Solaris 10 with SSL module enabled. But
configure command (./configure --prefix=/export/home/tomcat/nginx
--with-http_ssl_module) failed with following messages in autoconf.err.


=========================
checking for OpenSSL library

objs/autotest.c:4:25: openssl/ssl.h: No such file or directory
----------

#include 
#include 
#include 

int main() {
    SSL_library_init();
    return 0;
}

----------
gcc -D_FILE_OFFSET_BITS=64 -lsocket -lnsl -o objs/autotest
objs/autotest.c -lssl -lcrypto 
==========================

I have installed openSSL and is available on the PATH. 
OpenSSL> version
OpenSSL 0.9.7d 17 Mar 2004

Do I need to specify some kind environment variable for SSL library?
What's the default path Nginx will look for OpenSSL library?

Thanks,
William
