[openssl-users] Symbol(s) not found _TLSv1_2_method _BIO_test_flags

I did this step at a time to see what happens and here are the results:
With no paths modified, just bare code produces compile error
('TLSv1_2_method' was not declared at this scope) as expected because
openssl that comes osx 10.6 is older without such method - ok so far
Adding header paths to the 1.0.2h now compiles but then produces linking
Symbols(s) not found: _TLS1_2_method referenced from _main in main.o and
_SSL_CTX_new referenced - also means wrong path since it doesn't even see
the SSL_CTX_new, ok so far
adding new lib paths: and the libs to include m annually via -Lpath and
-llib flags :
/Developer/usr/bin/g++-4.2 -arch x86_64 -isysroot
(ps, the -filelist ...../testss3.LinkFileList contains single path to the
So to me this looks like 1.0.2h did not compile with TLSv1_2_method (and I
can not find the object that implements it either, only see that it is
referenced from s23_meth.o)
I am thinking there is an .o missing from linking of libssl.a but can't
find what object has the implementation of TLSv1_2_method
(I've even got rid of all the spaces in all the paths before compiling
openssl, make had issues installing across paths with spaces)
