Grrrr. What I wrote does not make any sense at all. :-(

It is plperl fault after all,

perl -MExtUtils::Embed -le ldopts

clearly states

-Wl,-R/usr/local/lib/perl5/5.6.2/mach/CORE -Wl,-E -L/usr/local/lib
/usr/local/lib/perl5/5.6.2/mach/auto/DynaLoader/DynaLoader.a
-L/usr/local/lib/perl5/5.6.2/mach/CORE -lperl -lm -lc -lcrypt -lutil

Note the -R here, and the absense of it in the lines you posted.
