>Description:
Even if I set COMPILER_RPATH_FLAG to the correct value on AIX, the lang/perl5 build has the problem of not setting the correct rpath for the perl binary. This is because in files/Policy.sh (which drives perl's Configure) only LDFLAGS and LDDLFLAGS are set up here:

# XCOFF targets need the path specified where libperl.a resides.
if $test "@OBJECT_FMT@" = "XCOFF"; then
        ldflags="@COMPILER_RPATH_FLAG@\${shrpdir} \$ldflags"
        lddlflags="@COMPILER_RPATH_FLAG@\${shrpdir} \$lddlflags"
fi

However the perl binary is built using the CLDFLAGS and CCDLFLAGS variables. This causes perl not to run because it cannot find libperl.a.
