I encountered the same problem and fixed the error in flex:

Download flex-2.5.23.tar.gz from ftp://ftp.uncg.edu/people/wlestes/

and apply the following patch, which was already sent to the maintainer of
flex and accepted by him. So, if there is flex-2.5.24.tar.gz or newer,
maybe the patch is already in.
