 Hiyas!
 
 I have found a workaround for this issue!
 
 Problem:
      The file:
 
      /usr/src/external/apache2/llvm/dist/llvm/include/llvm/Support/VCSRevision.h
 
      is missing and does not show up on a cvs update.  This leads to the command:
 
      ===> build.sh command:    ./build.sh -a x86_64 -m amd64 -D 
 /build/amd64/build -O /build/amd64/obj -R /build/amd64/release -T 
 /build/amd64/tools -j12 -x build
 
      ultimately failing with:
 
      --- IRSymtab.d ---
      #    create  libLLVMObject/IRSymtab.d
      CC=/build/amd64/tools/bin/x86_64--netbsd-c++ 
 /build/amd64/tools/bin/nbmkdep -f IRSymtab.d.tmp  --   -std=c++14 
 --sysroot=/build/amd64/build -I.

 /usr/src/external/apache2/llvm/librt/libLLVMObject/../../lib/../dist/llvm/lib/Object/IRSymtab.cpp 
 &&  mv -f IRSymtab.d.tmp IRSymtab.d
 /usr/src/external/apache2/llvm/librt/libLLVMObject/../../lib/../dist/llvm/lib/Object/IRSymtab.cpp:34:10: 
 fatal error: llvm/Support/VCSRevision.h: No such file or directory
         34 | #include "llvm/Support/VCSRevision.h"
            |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
      compilation terminated.
      nbmkdep: compile failed.
 
 Workaround:
      # cd /usr/src/external/apache2/llvm/dist/llvm/include/llvm/Support
      # ln -sf ../../../../../include/llvm/Support/VCSRevision.h .
 
 Solution:
      The solution would be to insure that VCSRevision.sh ends up in the
      right place.
 
      You may mark this closed, or you might want to leave it open until this is
      actually fixed.  Please note that neither a CVS fresh pull nor a CVS
      update seem to fix this problem.
 
 Please, also point port-amd64/54569 to this bug and close the former.
 
 				Thank you!
