problem building 5.12 release candidat -- pt_BR.utf8 problem

Hello,

I was trying to build the distribution tar.gz and rpm files for
a 5.12 release candidate and I ran into problems with
generating the pt_BR.utf8 documentation.
I don't know enough about how that is supposed to work.
I hope someone can help out here.

In a clean sandbox I executed sh bootstrap and ran into the following:

$ sh bootstrap
+ aclocal
/usr/share/aclocal/libgcrypt.m4:23: warning: underquoted definition of
AM_PATH_LIBGCRYPT
  run info '(automake)Extending aclocal'
  or see http://sources.redhat.com/automake/automake.html#Extending-aclocal
/usr/share/aclocal/ao.m4:9: warning: underquoted definition of XIPH_PATH_AO
+ 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

I attempted to rememdy that by modifying configure.in
(removing doc/info/pt_BR.utf8/Makefile from list of makefiles)
and doc/info/Makefile.am (removing $(PT_BR_DIR_UTF8)
from SUBDIRS).

After making those changes, sh bootstrap,
./configure --enable-<all-languages>,
and make dist-gzip run to completion.
However attempting to build rpms from the tar.gz file eventually
runs into problems too:

RPM build errors:
    File not found:
/var/tmp/maxima-5.11.99rc1-buildroot/usr/share/maxima/5.11.99rc1/doc/html/pt_BR.utf8
    File not found:
/var/tmp/maxima-5.11.99rc1-buildroot/usr/share/info/pt_BR.utf8
    File not found:
/var/tmp/maxima-5.11.99rc1-buildroot/usr/share/maxima/5.11.99rc1/doc/html/pt_BR.utf8
    File not found:
/var/tmp/maxima-5.11.99rc1-buildroot/usr/share/info/pt_BR.utf8

Looking at the tar.gz file, I see that the pt_BR files were
generated but not pt_BR.utf8. Dunno where to go from here.

Thanks for your help,

Robert
