[Fedora-packaging] %doc doesn't seem to use _defaultdocdir definition

[Daniel Letai]

Hi List,
I'm a newb at writing spec files, please bear with me.

I'm rebuilding a package for RHEL 6, so if this is the wrong list, 
please let me know.

I have redefined the prefix stack:
%global _prefix         /opt/%{name}/%{version}
%global _exec_prefix    %{_prefix}
%global _bindir         %{_exec_prefix}/bin
%global _sbindir        %{_exec_prefix}/sbin
%global _libexecdir     %{_exec_prefix}/libexec
%global _sysconfdir     /etc
%global _sharedstatedir /var/lib
%global _localstatedir  /var
%global _libdir         %{_exec_prefix}/%{_lib}
%global _includedir     %{_prefix}/include
%global _datarootdir    %{_prefix}/share
%global _datadir        %{_datarootdir}
%global _infodir        %{_datarootdir}/info
%global _localedir      %{_datarootdir}/locale
%global _mandir         %{_datarootdir}/man
%global _docdir         %{_datarootdir}/doc
%global _htmldir        %{_docdir}
%global _dvidir         %{_docdir}
%global _pdfdir         %{_docdir}
%global _psdir          %{_docdir}
%global _defaultdocdir  %{_docdir}

In configure:
         ../configure \
         --prefix=%{_prefix} \
         --exec-prefix=%{_exec_prefix} \
         --bindir=%{_bindir} \
         --sbindir=%{_sbindir} \
         --sysconfdir=%{_sysconfdir} \
         --datadir=%{_datadir} \
         --includedir=%{_includedir} \
         --libdir=%{_libdir} \
         --libexecdir=%{_libexecdir} \
         --localstatedir=%{_localstatedir} \
         --sharedstatedir=%{_sharedstatedir} \
         --mandir=%{_mandir} \
         --infodir=%{_infodir} \
         --docdir=%{_docdir} \
         ...

In make install:
make DESTDIR=%{buildroot} \
         prefix=%{_prefix} \
         mandir=%{_mandir} \
         infodir=%{_infodir} \
         docdir=%{_docdir} \
         install

The package completes without errors, resulting in RPMs, but In the 
output I see multiple instances of:
+ DOCDIR=~/rpmbuild/BUILDROOT/<rpm top buildroot 
dir>/usr/share/doc/%{name}-%{version}
+ export DOCDIR

and when installing the RPMs they install docs to /usr/share/doc.

when building and installing manually all is well (share/doc under /opt/...)
What am I doing wrong?
