Universal Binaries

[Jordan K. Hubbard]

There is a corollary to this, which is even if you do bundle up the  
appropriate MacPorts bits, you're now polluting a namespace that's  
not really under your control.  A commercial company who shall remain  
nameless found this out to their displeasure when they shipped  
software which installed (and relied upon) something in /sw/lib/...  
(they used Fink, obviously).   Unfortunately, the version they  
shipped in /sw had been customized in some way (if memory serves me  
correctly) and many Fink installations ended up installing their own  
version over it and blowing the commercial software up without even  
knowing why.   The commercial company had to ship an update which  
removed the dependency and I don't know how much that cost them in  
terms of engineering time and dollars, but I'm sure they regretted  
doing it in the first place.
