Source Code Build failure

```
What steps will reproduce the problem?
1.Get the Source using repo
2.Get rowboperf using git
3.get droidvnc using git

What is the expected output? What do you see instead?
Expected output: Built image.
But i see the following error:
build.xml: Failed to find version-tag string. File must be updated.
In order to not erase potential customizations, the file will not be
automatically regenerated.
If no changes have been made to the file, delete it manually and run the
command again.
If you have made customizations to the build process, the file must be manually
updated.
It is recommended to:
* Copy current file to a safe location.
* Delete original file.
* Run command again to generate a new file.
* Port customizations to the new file, by looking at the new rules file
located at /tools/ant/build.xml
* Update file to contain
version-tag: custom
to prevent file from being rewritten automatically by the SDK tools.

Updated file
rowboperf/3D/SDKPackage_OGLES2/Demos/ChameleonMan/OGLES2/Build/Android/proguard.

I manually removed the folder
"rowboperf/3D/SDKPackage_OGLES2/Demos/ChameleonMan/OGLES2/Build/Android/../../..
/../../Shell/OS/AndroidJNI/OGLES2ChameleonMan" and i see the following error
now:

Start with rowboperf/3D/SDKPackage_OGLES2/Demos/ChameleonMan/OGLES2/Build/Android/Makefile and ../../../../../Builds/OGLES2/AndroidGeneric/make_shared_lib.mak, then inspect why default.properties is missing and how proguard.cfg is regenerated. Reproduce the build on Ubuntu 10.04 with Android Gingerbread and confirm that the ChameleonMan Android library builds without the reported errors.
