Please check whether source/texk/web2c/web2c/web2c-lexer.c exists
(it should, and probably does). It also should not be older than
web2c-lexer.l in that same directory, and that is probably what goes
wrong: because it is older, make tries to create it anew, but you
don't have flex installed so the regeneration fails.

Quick fix:

   $ touch web2c-lexer.c
