That's why it is optional, however there is no such issue, all this 
incompatibility thing arised of interpretations by debian and the FSF, 
as far as the rest of the world. openSSL falls into the category of a 
"system library", twhich falls into the "special exception" clause which 
allows your GPL-ed program to link against GPL incompatible libraries 
which are shipped as part of the operating system.

Those  compiling and linking against incompatible library versions are 
doing it wrong, usually happends when users dont get proper packages 
from distributions or distributor-provided backports.
