That is unexpected, for certain.

Configure should have looked for a lexer (either flex or lex) and a 
compiler-compiler (either bison or yacc).  It appears configure found 
neither, but proceeded anyway.

The lex.ncmpi.c and ncmpigenyy.c files are generated from 
./src/utils/ncmpigen/ncmpigen.y and ./src/utils/ncmpigen/ncmpigen.l

I would like to draw your attention to this section of the README:

     - To build parallel-netcdf you will need some additional programs:
         - either yacc or bison
         - either lex or flex
       These are usually part of your operating system's development tools.

On debian, those packages would be 'flex' and 'bison' and you may as 
well install 'build-essential'

the good news is that those tools are only needed for ncmpigen.  If you 
really truly cannot install flex and bison, ncmpigen is not needed for 
libpnetcdf.a and pnetcdf.h to function.
