Of course. I meant only that Config_heavy.pl (required by Config.pm)
depends on correctly setup of ARCHFLAGS.

If you dont want the linker warnings about libperl.dylib has not the  
required
architecture and getting the ldopts with 'perl -MExtUtils::Embed -e  
ldopts' then
you have to specify the correct arch-flags in ARCHFLAGS to get the  
correct
ldopts (or strip out the '-arch xxx' from that output).
I think that plperl in postgres build system is the only place where  
ARCHFLAGS
is needed. i am not aware of other places.
for me these linker warnings are not a real problem, because i know  
the reason
for that and it is not affecting me or my work.

i will take a look.
