Built app won't launch, many libraries linked to missing dylibs (especially /opt)

[natevw]

The app build has finished now, but to run the app does not work. It crashes on launch:

Exception Type:  EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000

Application Specific Information:
dyld: launch, loading dependent libraries

Dyld Error Message:
  Library not loaded: /private/tmp/*/VisualSFM.app/Contents/Resources/opt/cairo/lib/libcairo.2.dylib
  Referenced from: /private/tmp/*/VisualSFM.app/Contents/Resources/bin/VisualSFM
  Reason: image not found

Here's what I had to do to get this to crash after load instead of before. Needless to say there's probably a better time/place to do this in the make scripts than after everything is finally linked:
