 Steps to reproduce:
 {{{
 wget bitcoin-0.6.0 from
 http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.0/bitcoin-0.6.0-linux.tar.gz/download

 tar xf bitcoin-0.6.0-linux.tar.gz
 cd bitcoin-0.6.0-linux/src/src
 make -f makefile.unix bitcoind
 }}}
 Steps to avoid error:
  * Error can be avoided by removing #if around #include <.../convert.hpp>
 in /usr/include/boost/program_options/detail/config_file.hpp
