I'm not positive about this, but I think in makefiles like this one, you
need to use the syntax $(prefix), and not ${prefix} (i.e. use parentheses
instead of braces).

All of these should be in the libstdc++ library. However, the makefile
is trying to link these with gcc rather than g++ or c++, which is probably
a big part of the problem. I suspect something went wrong during the
run of ./configure, most likely because your C++ compiler and libraries
aren't installed where the configure program expected to find them.

These error messages suggest that the C++ header files are not in the
standard location. The compiler found them OK, but things are messing
up and the linking stage. Is there a reason why you didn't just use
the egcs-c++ and libstdc++ RPM packages that came with Red Hat 6.2?
Those work fine with ht://Dig. I suspect that your setup as it is now
wouldn't work well with any software that needs C++.
