I recently acquired SPARC T4 hardware which allows me to run Solaris-11.4 CBE and this issue with net/tigervnc appears to be fixed by the recent Makefile change: # CMake build appends 'tigervnc', so this is not PKG_SYSCONFDIR CMAKE_CONFIGURE_ARGS+= -DCMAKE_INSTALL_SYSCONFDIR=${PKG_SYSCONFBASE} So this bug can probably be closed.
