And on FreeBSD 4.8 I get autoreconf errors as well:

configure.ac: 25: required file `./config.h.in' not found
doc/texinfo/Makefile.am:2: installing `doc/texinfo/texinfo.tex'
automake: configure.ac: installing `./depcomp'
autoreconf: automake failed with exit status: 1
 at /usr/local/bin/autoreconf line 359

automake-1.7.5_1
gettext-0.11.5_1
