I re-ran the test with erlang.mk patched to depend on host-openssl and
added back the --with-ssl flag when building the host erlang.

Indeed, I do not have this directory.

Aha!

    checking for static ZLib to be used by SSL in standard locations... no
    checking for OpenSSL >= 0.9.7 in standard locations... no
    configure: WARNING: No (usable) OpenSSL found, skipping ssl, ssh and crypto applications

Dang... It seems we have to tell it where to look for our own openssl.
Lemme see... Yes, we can say --with-ssl=PATH . I'll try that, and will
report later...

Thanks for the hint! :-)
