This is basically version 2.1.3 that James McIlree released for OSX
DP4. There's no need to put the pbproj file in an OSX directory, since it doesn't conflict with anything like the makefiles for multiple releases did.

Bison is required to compile this. There should be no warnings.

To compile first copy the PB.project and Makefiles from one

main source directory and then build it. For OSX, just use

the new project builder file.

Differences between 2.1.4 and 2.1.3

|

- It now understands framework install names and the framework
|
||||
search path, so you should be able to run it on apps or
|
||||
frameworks where the install name of the frameworks is not where
|
||||
the framework exists in the filesystem. The Omni frameworks,
|
||||
for example, change the install name.
|
||||
- You can set the ClassDumpDebugFrameworkPaths environment variable
|
||||
to see the steps it's going through to find the frameworks. It
|
||||
spits out a lot of stuff, but it may be useful for someone. With
|
||||
zsh, you can do this:
|
||||
ClassDumpDebugFrameworkPaths=YES class-dump /System/Applications/MailViewer.app
|
||||
of the Nextstep, Openstep, Rhapsody or OSX directories into the

main source directory and then build it.
