kdebase SVN FTBFS

Hello, I'm compling TDE SVN rev 1260891 on RHEL 6. I get the following error during "make install": ============== -- Installing: /home/albator/rpmbuild/BUILDROOT/trinity-kdebase-3.5.12.99.1260891-0.el6.opt.x86_64/opt/trinity/bin/kdmtsak CMake Error at kdmlib/cmake_install.cmake:131 (FILE): file RPATH_REMOVE could not remove RPATH from file: /home/albator/rpmbuild/BUILDROOT/trinity-kdebase-3.5.12.99.1260891-0.el6.opt.x86_64/opt/trinity/bin/kdmtsak Error opening file for update. Call Stack (most recent call first): cmake_install.cmake:43 (INCLUDE) make: *** [install] Error 1 make: Leaving directory `/home/albator/rpmbuild/BUILD/kdebase/build' ============== The file"opt/trinity/bin/kdmtsak" exists but is not writable. I suppose that's why the RPATH_REMOVE macro fails: -r-s--x--x 1 albator albator 108807 26 oct. 20:04 /home/albator/rpmbuild/BUILDROOT/trinity-kdebase-3.5.12.99.1260891-0.el6.opt.x86_64/opt/trinity/bin/kdmtsak (Note: RPM building is done as non-root user.)
