Thank you for the clarification, Andreas!  I completely neglected to 
think about the fact that libwraster5 and my proposed libwraster5v2 
would both be trying to install the same file.

Option 2a sounds good to me.  Feel free to revert my last few commits if 
you get to it before I do.

Just to clarify, would the best course of action for upstream to be to 
go ahead and bump the soname for libwraster to 6 for the next release? 
If so, I can prepare a patch.
