Android: ADB not loading

When I want to create android project I get the following message. I cant proceed anyway. Please anybody help me. My system is ubuntu 10.10

Failed to get the adb version: Cannot run pr开发者_如何学Cogram "/home/mak/Android/Android SDK/android-sdk-linux_x86/platform-tools/adb": java.io.IOException: error=13, Permission denied

Looks like the /home volume is mounted without the exec permission. Examine your /etc/fstab.
