[Libreoffice] Segmentation fault in building tail_build project

Hi all,
I have just downloaded the latest source code from GIT, following the
developer guideline in making the build. But it failed in tail_build
project. When attempting the individual build on tail_build project, I get
this output "No environment set!".

Below are a snapshot of the output during the build from top level, hoping
this could give out some hints on fixing this issue.

-----------------------------------------------------------------------
        Oh dear - something failed during the build - sorry !
  For more help with debugging build errors, please see the section in:
            http://wiki.documentfoundation.org/Development

  internal build errors:

ERROR: error 65280 occurred while making
/home/huahsin68/workspace/LibreOffice/core/tail_build/prj

 it seems that the error is inside 'tail_build', please re-run build
 inside this module to isolate the error and/or test your fix:
-----------------------------------------------------------------------

/bin/bash
cd /home/huahsin68/workspace/LibreOffice/core
source ./Env.Host.sh
cd tail_build
make clean # optional
make -r

when the problem is isolated and fixed exit and re-run 'make' from the
top-level
make: *** [build] Error 1


THanks @!
