CocoaPods-App cannot be built when there are spaces in the path

[endocrimes]

The pkg-config build step doesn't seem to be escaping paths correctly.

Interesting, so it seems to be an internal configure (?) issue, as the path is given to the configure script in a quoted fashion.

Can you try fixing it by shell escaping the path when passing it to the configure script? E.g.

$ ruby
require 'shellwords'
puts '/foo bar/baz'.shellescape
ctrl^d

Which results in:

/foo\ bar/baz
