Details:

On SUSE 11.1, logged in as root, using BASH-3.2.

Downloaded and extracted AVRDUDE-5.6.

The configure script reports that flex/lex is missing but does not abort.
This is easy to miss.

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 ranlib... ranlib
checking for tputs in -ltermcap... no
checking for tputs in -lncurses... yes
checking for readline in -lreadline... yes

Running make afterwards gives an error that is hard to figure out:

sed '/^#/ s|y\.tab\.c|config_gram.c|' y.tab.c >config_gram.ct && mv
config_gram.ct config_gram.c
rm -f y.tab.c
