I'm well aware of the evils of LD_LIBRARY_PATH. But that was not my question, which was: why does Perl on Linux seem to require that LD_LIBRARY_PATH be defined before the script starts rather than being defined in a BEGIN block before DBD is loaded?
P.S. If anyone can tell me how to do the equivalent of setting rpath in the .so files produced by AIX's xlc compiler, then I could go that route. But since I currently have to set LIBPATH for AIX (which I can set *inside* the script as opposed to prior to running the script like I have to do on Linux), then I'll stick to trying to set LD_LIBRARY_PATH on Linux.

But are you aware the that is how LD_LIBRARY_PATH works for all programs? That its not a perl variable?
For every software Why? question, the answer is simple, because its written that way :)
The LD in LD_LIBRARY_PATH stands for one of the few/many "ld.so" , there is no PERL_ prefix
All docs I read about LD_LIBRARY_PATH mention its for testing/debugging...
If that answers the question, then great :)
