Compiling Python 3.3.2 on CentOS 6.4 - unable to find compiled OpenSSL?

[Victor Hooi]

Hi,

We have a machine running CentOS 6.4, and we're attempting to compile Python 3.3.2 on it:

	# cat /etc/redhat-release
	CentOS release 6.4 (Final)

We've compiled openssl 1.0.1e 11 by hand on this box, and installed it into /usr/local/:

	# openssl
	OpenSSL> version
	OpenSSL 1.0.1e 11 Feb 2013
	 
	# ls /usr/local/include/openssl/
	aes.h       blowfish.h  cmac.h      crypto.h   dso.h     ec.h      hmac.h      md4.h      obj_mac.h      pem2.h    rand.h    safestack.h  ssl23.h  symhacks.h   ui.h
	asn1.h      bn.h        cms.h       des.h      dtls1.h   engine.h  idea.h      md5.h      ocsp.h         pem.h     rc2.h     seed.h       ssl2.h   tls1.h       whrlpool.h
	asn1_mac.h  buffer.h    comp.h      des_old.h  ebcdic.h  e_os2.h   krb5_asn.h  mdc2.h     opensslconf.h  pkcs12.h  rc4.h     sha.h        ssl3.h   ts.h         x509.h
	asn1t.h     camellia.h  conf_api.h  dh.h       ecdh.h    err.h     kssl.h      modes.h    opensslv.h     pkcs7.h   ripemd.h  srp.h        ssl.h    txt_db.h     x509v3.h
	bio.h       cast.h      conf.h      dsa.h      ecdsa.h   evp.h     lhash.h     objects.h  ossl_typ.h     pqueue.h  rsa.h     srtp.h       stack.h  ui_compat.h  x509_vfy.h

However, when we try to build Python 3.3.2, it can't seem to find the SSL installation:

I also tried editing the Modules/Setup.dist file, no luck there either.

Any thoughts on what we're doing wrong?
