I've had a problem with the -WithInstaller framework since around 0.7.4 came out. The nibs are corrupt - won't open in IB - but work if you copy them over from its source distribution. Additionally, at some point in the build process, the framework's symlinks for Resources and Current and so on seem to turn into empty folders.
I've talked to Chris about this and he's agreed that it's very strange, but we're both at odds as to where the problem appears and why. Does any other project linking with -WithInstaller have this problem?
