It looks like flex and/or bison are missing on your system.

Check the output of `configure', if those utilities are *installed*,
there should be lines like these:

checking for flex... flex
checking for yywrap in -lfl... yes
checking lex output file root... lex.yy
checking whether yytext is a pointer... yes
checking for bison... bison -y
