Details:

avrdude 5.4 original tar file is used. The configure script
checks for flex, reports "no" but does not stop working. The
make run afterwards crashes.

from running configure:
------------
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ANSI C... none needed
checking for style of include used by make... GNU
checking dependency style of gcc... gcc3
checking for a BSD-compatible install... /usr/bin/install -c
checking for bison... bison -y
checking for flex... no
checking for lex... no
checking for yywrap in -lfl... no
checking for yywrap in -ll... no
checking for ranlib... ranlib
checking for tputs in -ltermcap... no

WARNING: `flex' is missing on your system.  You should only need it if
         you modified a `.l' file.  You may need the `Flex' package
         in order for those modifications to take effect.  You can get
         `Flex' from any GNU archive site.

System: Ubuntu Linux 7.04. installing flex solves the underlying
problem.
