Do you have the 'algorithm' file on your system, in /usr/include/c++/v1?
And is the rest of libc++ correctly installed?  You should have the
following libraries:

/usr/lib/libc++.a
/usr/lib/libc++.so
/usr/lib/libc++.so.1
/usr/lib/libc++_p.a

Another possibility is that you are assigning to CFLAGS and/or CXXFLAGS
incorrectly.  Can you please post your make.conf and src.conf files?

Last but not least, from which version of FreeBSD are you building?  An
older copy of -CURRENT, or some -STABLE branch?
