- Conflict between library -dev packages, and -dev packages to 
  depend on correct version of other -dev packages.
	- Would allow valid setups
	- Packages may become FTBFS, but when they are fixed, 
	  packages work.

see libpkg-guide for fuller story.
And I think it is one way of going without versioned symbols.

Using versioned symbols is a workaround which is, although
available within all Debian architectures, not available on 
everywhere, and considering free software as a whole, 
it might be better to notify upstream of library inconsistency.


libssl went against guidelines shown libpkg-guide in that 
it replaced libssl-dev (0.9.6) with libssl-dev (0.9.7), just like
libpng-dev (for 3) replaced libpng-dev (for 2)
