i've had something like this happen before -- you didn't start with
a previous version of config.cache or something?

i just tried uninstalling flex and reconfiguring, and the error
was similar:  "checking if :  is really flex" or something like
that.  so the ':' is a placeholder being left around by the
configure script.  i'm sure you'll find a "LEX = :" line near
the top of filters/makefile, and i suspect it gets there because
there's a test in configure (in mine, near line 3206) which says:
    test -n "$LEX" || LEX=":"

this looks like it's going to let configure succeed with LEX equal
to ":".

after that, the maze of passages gets very twisty, and my lantern
starts to dim.
