Installing and Testing out your own crowd-sourced App with PyBossa

Testing PyBossa with a Virtual Machine :

Install Virtualbox and Vagrant first.

Problem : The 'vagrant up' fails on WinXP while installing 'hashicorp/precise32' dependency.
Following error message is seen : 

Cause :  This is caused by missing or failure in running bsdtar.exe.
For More Details see :
1) Install Mingw with bsdtar.exe
2) "However, installing MinGW for the bsdtar.exe, brought up another issue.
bsdtar.exe wouldn't run because it needed 'msys-lzma-1.dll' but 'msys-lzma-5.dll' was available.
Just copied and renamed to expected filename and it worked!!"

Now precise32 installs and 'vagrant up' succeeds.

Next step

Problem : Running the 'source' script fails
Cause : bash requires usage of ./scriptname to execute script in current directory.
Solution : Just changing the docs line 'source' to 'source ./' fixes the problem.

Problem : 'source ./' still fails
Cause : It gives errors for trailing ^M characters in the script, DOS line-feed chars.
Solution : Editing the file and removing trailing ^M characters solves the problem.
