winton / externals

It looks like there is a special character here: http://github.com/winton/externals/blob/1d2525e1ae53002041d5ba87426b0e8a1b52e2b3/lib/externals/repository.rb#L35 and on lines 53 & 91. Changing these ` to " fixes this issue, even though the tgz files are not visble, it works.

Hey Mario,

Surrounding a string in those special characters actually tells Ruby to execute that string as a system call. It is similar to using the system() call:

The slash next to the colon does look odd. I don't have a PC, so anything you figure out helps a lot.

Thanks,
Winton
