 # The  output  of  configure  will  tell you the versions of the OpenSSL

 # checking OpenSSL header version... 90604f (OpenSSL 0.9.6d 9 May 2002)
 # checking OpenSSL library version... 90602f (OpenSSL 0.9.6b [engine] 9 Jul 2001)
 # checking whether OpenSSL's headers match the library... no

 # Now run findssl.sh. This should identify the headers and libraries

 # libraries  and headers used and adjust your CFLAGS or remove incorrect
