#13 configure.in must check for boost/lexical_cast

[Kevin Nowaczyk]

Currently there is no check for boost/lexical_cast in
configure.in. This is because I can't figure out how
to check for a single header file. The info file makes
it seem like AC_CHECK_HEADER would work, but it
doesn't. I may have to write to the automake mailing list.

AC_Check_HEADER works for everthing except .hpp files.
