DYLD_LIBRARY_PATH problem

[David Reiser]

This is more of a mac + fink interaction problem than a  
straightforward bug, so I thought I'd bring it up here.

In the current state of 2.1.x, I can't run a standard fink-built  
gnucash because setting DYLD_LIBRARY_PATH clobbers something which  
goes looking for libjpeg in the wrong place at runtime (building  
works with no complaints).

I can patch around it pretty easily by substituting  
DYLD_FALLBACK_LIBRARY_PATH for each instance of DYLD_LIBRARY_PATH. My  
limited understanding of the difference is that the _fallback_ choice  
adds the directory to the end of the search path and the other  
prepends the directory to the front of the path.

When I brought up my situation among the fink folk, they opined that  
setting DYLD_LIBRARY_PATH is, in general a bad idea if there is any  
way to avoid it. The first quick and dirty fix is the  
DYLD_FALLBACK_LIBRARY_PATH approach.

And Peter O'Gorman offered:

Does his suggestion sound easily doable? (If you tell me what he  
means by removing it from (which) wrapper; and tell me how to make a  
distribution tarball from my svn co, I can test it before it's  
committed.)

I hate to admit it, but I still don't really understand wrappers much  
at all...

Thanks.
