I'm really stuck. I previously installed the Tegra Development Pack and it was all working flawlessly. All of the samples built and ran with no errors. I messed around with the samples a little too much and they stopped working. I didn't have a backup so I decided that the easiest option would be to uninstall the Tegra Development Pack and reinstall it. Since reinstalling it, I am unable to get the samples to work.
Here is what the console outputs:
09:56:57 **** Incremental Build of configuration Default for project OpenCV Sample - face-detection ****
/bin/bash /ndk-build NDK_DEBUG=1 V=1
/bin/bash: /ndk-build: No such file or directory
09:56:57 Build Finished (took 81ms)
My build path is set to what the Pack set itself to: ${CYGWIN_HOME}/bin/bash
If I directly point to ndk-build: /Users/jordan/NVPACK/android-ndk-r8d
10:04:56 **** Incremental Build of configuration Default for project OpenCV Sample - face-detection ****
/Users/jordan/NVPACK/android-ndk-r8d /ndk-build NDK_DEBUG=1 V=1
10:04:56 Build Finished (took 87ms)
I then clear & build all projects. However the error is still present.
OpenCV Manager is correctly installed on my device. I can verify this is correct because if I install the Face-Detection APK that I built previously from the sample, it runs.
I don't understand why it worked previously but not now considering that I haven't changed anything?
Here is the LogCat output:

I would greatly appreciate any help offered in getting this working again.
Edit: OS X 10.8.4 - Nexus 4 on 4.3 & Xperia SP on 4.1.2
I'm going to try installing the Tegra Development Pack on to my XP Virtual Machine next.
Update: Works flawlessly again on my XP Virtual Machine. At least now I can continue my work.
Looks for whatever reason, you don't have the NDKROOT point to the ndk path when you launched eclipse.
Check: 1. Whether you installed ndk by TADP. 2. Check ~/.MacOSX/environment.plist (open by xcode), ~/.bash_profile, ~/.bash_rc. The TADP installer shoud write the variable NDKROOT for you, in those files.
