Thanks Tom, I can see your point. With the right change to LD_LIBRARY_PATH,
I can make `ldd plperl.so` point to my Perl, but as you say, I'm probably
playing with fire to expect it all to be 100% compatible between Perl
5.10.1 (Centos 6 default) and 5.30.1 (mine).
It'd be nice if we could set Perl at server start time, but I can see how
it might not be possible.
I'll see about making this extension versus just recompiling the whole thing.
I don't recall building Pg to be all that hard, I was just hoping to avoid it.
-OR- I blast it from orbit and rewrite the 2 plperl functions so I don't need the
extension. Decisions ... decisions ...
Thanks!
Kevin
