You gave the option 'shared'.  Normally, that would give you shared libraries.
Unfortunately, the OpenSSL configuration doesn't include shared library support
for this platform yet, so it will pretend you gave the option 'no-shared'.  If
you can inform the developpers (openssl-dev\@openssl.org) how to support shared
libraries on this platform, they will at least look at it and try their best
(but please first make sure you have tried with a current version of OpenSSL).
