So, we have a mystery to solve.

First note that the patch changes one line and adds one line immediately 
before it:

-target_link_libraries(kio_nfs   ${KDE4_KIO_LIBS})
+include_directories(/usr/include/tirpc)
+target_link_libraries(kio_nfs   ${KDE4_KIO_LIBS} tirpc)

to the file:

kioslave/nfs/CMakeLists.txt

so it should be easy to check to see if Gentoo added this patch.

If not, and since the GIT and the tarballs do not have this change, this 
is somewhat of a mystery.

I presume that Gentoo installs: "libtiprc" (Fedora does).  You might 
want to check that and if it is patched.  BLFS has a patch for that:

http://www.linuxfromscratch.org/blfs/view/svn/basicnet/libtirpc.html

bit I think that it only changes NIS.

Although, IIRC, GLibC no longer contains RPC, it still installs:

/usr/include/rpc/rpc.h

and that is the header that an unpatched: "kde-runtime" module finds 
rather than:

/usr/include/tirpc/rpc/rpc.h

If the unpatched: "kde-runtime" module builds correctly, it would have 
to mean that either GLibC or LibTiRPC has been patched or possibly GLibC 
has used an additional configuration parameter.  I installed with:

--prefix=/usr --disable-profile --enable-add-ons --enable-kernel=2.6.25 
--libexecdir=/usr/lib/glibc

Does Gentoo add anything?
