Defining the variable only when HAVE_SSL is declared sounds correct.  The real 
issue is appears to be the reference to ssl_version at line# 312.  I believe the 
#endif at line# 309 should be #else and the #endif should be moved to just 
before the break at line# 320.

BTW, if you want SSL support, install libssl-dev and re-run configure.  Make 
will then succeed ;-)
