clean build fails, trouble with doc/info/pt_BR.utf8

Hello,

I have tagged a release branch (RELEASE-5_15_0-BRANCH) in cvs.
When I attempt to do a clean build (after cvs get in an empty directory)
I get complaints from the automake stuff about pt_BR.utf8.

$ sh bootstrap
+ aclocal
+ automake --add-missing --copy
configure.in: installing `./install-sh'
configure.in: installing `./missing'
doc/info/Makefile.am:22: required directory doc/info/pt_BR.utf8 does not exist
configure.in:6: installing `./config.guess'
configure.in:6: installing `./config.sub'
configure.in:740: required file `doc/info/pt_BR.utf8/Makefile.in' not found
+ autoconf

$ ./configure --enable-clisp
[...]
configure: creating ./config.status
config.status: creating Makefile
config.status: error: cannot find input file: Makefile.in

I think we've been through this before. Can someone fix this?
I can't tell what's going on.
