Perl is also gone, but you likely have a ports perl in your PATH anyway. The process of building FreeBSD-10 _should_ work with 9's historic gcc, though you can go safe and setup clang and it's libc++ to become the default in 9-stable by using WITH_CLANG_IS_CC and WITH_LIBCPLUSPLUS just to be safe. As the c++ runtime library was exchanged, you need to rebuild all (c++) ports before running make delete-old-libs of the updating process (however I would recommend just to rebuild *all* installed ports). www/squid3* doesn't build with clang over here, but that can be workarounded by adding "--disable-strict-error-checking" into the port Makefile's CONFIGURE_ARGS. > BTW, no COMPAT_FREEBSD8 or COMPAT_FREEBSD9?

Also, the FreeBSD-10 kernel can run a FreeBSD-9 userspace without any modifications (I'm running a 9-jail on a GENERIC 10 host over here).
