I found a GPL-ed SIP client for Mac, Blink. I'd like to build it from source since the binaries are only available as paid download.

Just FYI i'm studying programming at university but have no experience in building complex application from source.

After downloading the content of the repository i opened the Xcode project and tried to build on OS X 10.7, Xcode 4.2.1. Unfortunately the build fail with 1 error and many warnings Most of the warnings are like this:

Attribute Unavailable: Custom Identifiers in Interface Builder versions prior to 3.2

The error message is:

Apple Mach-O Linker (ld) Error
Command /Developer/usr/bin/clang failed with exit code 1

preceded by the warning

Apple Mach-O Linker (ld) Warning
directory not found for option '-L/Users/Sergio/Downloads/Blink/devel.ag-projects.com/repositories/public/blink-cocoa/Distribution/Frameworks'

I notice that in the list of required files i have this files missing:

Dependencies/Frameworks
libgcrypt.11.6.0.dylib
libgcrypt.11.dylib
libgnutls-extra.26.dylib
libgnutls.26.dylib
libgpg-error.0.dylib
libintl.8.dylib
liblzo.1.dylib
libtasn1.3.dylib

Dependencies/Resources

Frameworks/Linked Frameworks

It should be possible to download these files somewhere. Unfortunately googling did not help. There's no documentation on the project site.
