I wish to test and build bro for debian/gnu linux but I ran into a couple of problems... hope somebody can help me out.

1.after ./configure I get something like:
creating ./config.status
creating Makefile
creating aux/hf/Makefile
sed: can't read ./aux/hf/ No such file or directory
creating aux/cf/Makefile
creating config.h
config.h is unchanged

my question is, should I be worried about sed not being able to read ./aux/hf/

2.after ignoring the above error, continuing with make fails at

sup3r:/idsbro/bro-pub-0.7a90# make
c++ -I. -O -Ilinux-include -c In function `void do_fmt(const char *&, Val *, ODesc *)': implicit declaration of function `int localtime(...)' implicit declaration of function `int strftime(...)'
make: *** [Func.o] Error 1

is that related to the first problem or it's another problem I need to deal with and I honestly don't know how...

thanks for any help
