Pycryptopp Gives Cryptic (pun intended) error message when it can't find g++

[arch_o_median]

The following was generated by: python setup.py install:

Running pycryptopp-0.5.15/setup.py -q bdist_egg --dist-dir /tmp/easy_install-p2hE68/pycryptopp-0.5.15/egg-dist-tmp-8gF_HB

darcs failed:  Not a repository: . (./_darcs/inventory: openBinaryFile: does not exist (No such file or directory))
setup.py darcsver: Failure from attempt to find version tags with 'darcs changes', and pycryptopp/_version.py already exists, so leaving it alone.

This means you have no C++ compiler. On Debian/Ubuntu?, sudo apt-get install g++. We can close this ticket if we can extend pycryptopp's setup.py to catch this error and emit a clearer error message like "Error: no C++ compiler found".

Another improvement would be to generate binary eggs of pycryptopp for more platforms, including Linux. Then it would not attempt to build it from source, and therefore it would not require a C++ compiler.
