According to the main configuration utility (parameters for openssl include and lib directories) and accoring to Alan DeKok's email from May 16 (How to link to openssl if two versions of libssl are on the system, when building FreeRadius on Debian wheezy 7.4?) this should be possible:

CentOS has own packages for development purposes, for example openssl-devel; to be sure that FreeRADIUS does not include the wrong header file, I have removed this package. Thus, FreeRADIUS will either take the correct file or report a missing file.

Yep, to make them consistent with every other library the server uses.

Concerning the modules, rlm_otp is the only module which offers configuration parameters for OpenSSL directories, and this module still uses the old parameter names in 3.0.3 and in the git version from today. There is an easy workaround for this problem: Simply pass both (old and new) parameters to the main configuration script!
rlm_otp doesn't need a configure script, it should have been using the results of the main configure script.
I've removed the rlm_otp configure script.

You'd set it in Make.inc.
With v3.0.x head
Works for me with v3.0.x...
./configure --with-openssl-lib-dir=/usr/local/opt/openssl/lib --with-openssl-include-dir=/usr/local/opt/openssl/include
checking OpenSSL library and header version consistency... library: 1000108f header: 1000108f... yes
