Hi Aaron,

this is an interesting problem. There are a two solutions available, 
however. But basically, how do you plan to install the application? IMO 
embedded frameworks only make sense in a strictly defined environment 
like Mac OS X. On Mac OS X, installing an application is as easy as 
dragging it somewhere - or even launch it from a DMG file that you just 
downloaded.

On GNUstep the first problem is the layout of the GNUstep tree - 
flattened or not flattened.

1)
If it's not flattened then there's a shell script which - depending on 
the library combo and architecture - launches the appropriate 
executable. You could modify this shell script to include your 
"embedded frameworks" (which are libraries) in it's library search path 
by utilising the information that you have at launch time of the script 
(GNUstep environment, executable's directory). After that launching the 
application including referencing the embedded frameworks should work.

2)
If the GNUstep tree is flattened (which is now the default) you have to 
modify the executable to be a shell script and do as in 1), then launch 
the executable.

Both approaches should be easy to integrate with your Makefiles in 
after-<YOUR_TARGET>-all:.

The general question however remains: Is it possible to create binary 
packages for GNUstep at all? IMO this is only possible if you assume a 
default GNUstep installation - it will surely break with my 
installation which is not flattened. But it's probably reasonable to 
assume the default anyways.

Cheers,

  Marcus
