rebuild rpm rpm-3.0.5-9.6x.src.rpm no go

[Harry Putnam <reader newsguy com>]

Running Redhat 6.2 
rpm-3.0.4-0.48

Anyone else have trouble rebuilding the rpm-3.0.5-9.6x source rpm?

My attempt ended with a bad exit status.  I noticed this early on in
the build process when a perl Makefile is being generated, not sure if
it is significant:

[...]

  creating python/Makefile
  creating perl/Makefile
  sed: can't read ./perl/Makefile.in: No such file or directory
  creating perl/Makefile.PL
  sed: can't read ./perl/Makefile.PL.in: No such file or directory

[...]

There were quite a few `warnings' about `declarations' through out and
a warning close to the end about a size mismatch:
      (messages wrapped for clarity)

  /usr/bin/../lib/libc.a(explodename.o): In function `_nl_explode_name':

  /usr/src/bs/BUILD/glibc-2.1.3/intl/explodename.c:73: multiple
  definition of `_nl_explode_name'
  
  ./intl/libintl.a(explodename.o)(.text+0x0): first defined here
  
  /usr/bin/ld: Warning: size of symbol `_nl_explode_name' changed from
  563 to 553 in explodename.o
