The package in debian might be called 0.9.8c, but it actually takes the
security updates from 0.9.8d. There is only 1 change in d that isn't in
the Debian package.

The package in Debian is compiled with symbol versioning which upstream
doesn't do. This is to avoid problems on library upgrades.
Everything that that links to openssl in Debian knows that it was using
those symbol versioning. Since you now don't have have those symbols,

In Configure this change:
+$shared_ldflag .= " -Wl,--version-script=openssl.ld";
And you also need the openssl.ld file.
But can I suggest you just use the Debian package and upgrade that,
instead building your own? You might run into other problems using the
upstream version that the Debian version doesn't have.
