Your system should not be running flex at all; the flex-generated files 
are included in CVS and in the tarball release of 1.2.0-beta1. If you 
don't have them, you have a broken download/checkout.

Additional info:
This is on the 1.0.9 CVS. I failed to include that info on my original
post. I have not tried the tarball.

I have also downloaded the 1.2.0-beta1 tarball and it compiles and
installs properly.
