Because you make it hard to reproduce the issue. E.g. my head scratch
box definitely will not be put to evolution-data-server compilation to
reproduce this.

Ok, this is useful. But, on the HEAD from Jul 2, I cannot reproduce it,
with conftest.c and command line above. As well as on the stable/8 that
is approx. one month old.
On both systems, MD2_* symbols are resolved by libcrypto.so. Check
your instance, do the symbols appear in the library ?
As a long shot, do you have openssl 1.0 installed from ports ?
Note the -L /usr/local/lib switch, that causes -lcrypto to be resolved
from /usr/local/lib, if present. AFAIR, 1.0 removed MD2.
