Pardon me if this sounds dumb, but what possible use are those directives,
then?

That's one thing I don't think we've tried. What I still don't understand is
how PerlSetEnv variables ARE present in the Apache process handled by that perl
handler, but not in the perl handler code itself.
Even setting "%ENV{'LD_LIBRARY_PATH'}= <path to libs>;" in the perl handler
code itself fails, and if the handler code cannot alter it's own process, then
I'm stuck.
I'll try recompiling DBD::Oracle.
