That's a problem on our part. No, flex and bison are not required
for compiling from source, since the generated C files from the lex
and yacc files are distributed with the source tarball. We never
noticed it because we all happen to have flex and bison installed.
Flex and bison are required for developers, or anyone wanting
to modify the *.y and *.l files, but not for simply compiling from source.

I'll work on a fix so that the next version of Ethereal won't have
that configuration problem. Can you install flex? That would be
your quickest solution, until I get time later today/tonight to
work on a fix.
