different or older compiler you are on your own. Note that you may have to
use the same compiler you compiled CLN with because of differing
name-mangling schemes.
The pkg-config utility is required for configuration, it can be downloaded

To build the GiNaC tutorial and reference manual the doxygen utility
(it can be downloaded from http://www.stack.nl/~dimitri/doxygen) and
TeX are necessary.
