I cannot build from source. The README says to simply do the usual "./configure && make && make install", but there is no "configure" script to run. I ran 'autoconf' which generated the 'configure' script (this should be documented). I also ran 'autoheader' which generated the "config.h" (also should be documented). Running './configure' then gave me a Makefile, but it complained that I was missing YACC. That should probably be caught in the 'configure' script. Then it complained I was missing flex. That should also be caught in the 'configure' script. At this point a build gives me an error complaining about a missing lex file (y.tab.c:1393: undefined reference to `bdconfig_lex'), so I gave up and downloaded the Debian source package and rebuilt from there. I have not been able to see what was done to correct the undefined reference to `bdconfig_lex', but the Debian source package seems to work.
