[erlang-questions] Building erlang R1603-1 on CentOS - unable to load crypto library

Howdy fellow Erlangers,

I have built many many Erlang systems from source, but today I am having a very unusual problem in that no matter how I build erlang, it fails to link properly to the crypto libraries. 

Here is the issue:

[ otp_src_R16B03-1]$ erl
Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.4  (abort with ^G)
1> l(crypto).
{error,on_load_failure}

=ERROR REPORT==== 2-Feb-2015::18:26:50 ===
Unable to load crypto library. Failed with error:
"load_failed, Failed to load NIF library: '/home/adam-dev/erlang/R16B03-1/lib/erlang/lib/crypto-3.2/priv/lib/crypto.so: undefined symbol: EC_GROUP_new_curve_GF2m'"
OpenSSL might not be installed on this system.

=ERROR REPORT==== 2-Feb-2015::18:26:50 ===
The on_load function for module crypto returned {error,
                                                 {load_failed,
                                                  "Failed to load NIF library: '/home/adam-dev/erlang/R16B03-1/lib/erlang/lib/crypto-3.2/priv/lib/crypto.so: undefined symbol: EC_GROUP_new_curve_GF2m'”}}

The shared library is there:

[ otp_src_R16B03-1]$ ls -la /home/adam-dev/erlang/R16B03-1/lib/erlang/lib/crypto-3.2/priv/lib/crypto.so
-rwxr-xr-x. 1 adam-dev adam-dev 172170 Feb  2 18:25 /home/adam-dev/erlang/R16B03-1/lib/erlang/lib/crypto-3.2/priv/lib/crypto.so

I did find this in the log:

The rest of the details. I have a brand spanking new CentOS install:

[ otp_src_R16B03-1]$ uname -a

And here is my configuration:

[ otp_src_R16B03-1]$ ./configure --prefix=/home/adam-dev/erlang/R16B03-1 --enable-ssl=yes --enable-kernel-poll --enable-smp-support --enable-threads --with-odbc=yes --enable-m64-build

Configure finds everything ok. Here is snippet of the output relating to ssl:

checking for OpenSSL >= 0.9.7 in standard locations... /usr
checking for OpenSSL kerberos 5 support... yes
checking for krb5.h in standard locations... found in /usr/include
checking for ssl runtime library path to use... /usr/lib64:/usr/local/lib64:/usr/sfw/lib64:/opt/local/lib64:/usr/pkg/lib64:/usr/local/openssl/lib64:/usr/lib/openssl/lib64:/usr/openssl/lib64:/usr/local/ssl/lib64:/usr/lib/ssl/lib64:/usr/ssl/lib64:/usr/local/lib:/usr/sfw/lib:/usr/lib:/opt/local/lib:/usr/pkg/lib:/usr/local/openssl/lib:/usr/lib/openssl/lib:/usr/openssl/lib:/usr/local/ssl/lib:/usr/lib/ssl/lib:/usr/ssl/lib

make and make install complete without error. Another snippet:

Any help would be greatly appreciated!
