When gcc sees "-lssl" it looks for libssl.so then crawls the symlink 
tree above.

As long as we have the .0 -> 0.9.8 symlink in place, gcc will link 
against the new one, which openssl 0.9.8 spell should do already.  The 
libssl.so.0.9.7 then simply exists for things not relinked yet.

I think if we simply add a echo '^/usr/lib/libssl.so.0.9.7$' > protected 
in the libssl-so-0-9-7 spell and have BUILD be "true" and INSTALL be 
"touch /usr/lib/libssl.so.0.9.7" with the new openssl depending on this, 
it would work out.  (although I see this as very dirty :) )
