Hi Emile, Try commenting the PACKAGE and VERSION macro definitions in the libffi header files on your system. (/usr/include/ffi.h probably?) You should have got compiler warnings about redefinition of these macros. This is a bug in libffi. You should provide more details about your platform (GNU/Linux version (or BSD?), processor, gcc vdrsion used, ...) in the future. It helps people to help you...
