Hi RP,
If a recipe does need perl-native but we fail to realize that, the host's perl (e.g. /usr/bin/perl) will be used -- this will further hinder us from realizing the recipe needs perl-native.

As to bug #968, the build failure happens because perl-native's do_populate_sysroot has begun but hasn't finished. If perl-native hasn't started to populate_sysroot, running gnu-configize won't fail since host's perl will be used.

so I've 3 questions:
1) in poky how to exclude host's perl from PATH? need to write a python function to filter out various possible host perl paths? e.g., ~/bin/perl, /usr/local/bin/perl, /usr/bin/perl, /bin/perl,... too many paths...

2) how to identify the recipes that need perl-native? I think we have to identify them manually one by one? This is time comsuming?

3) Even if we solve the above 2 issues, we still need to add perl-native into the recipes' (that need perl-native) DEPENDS, correct?

I'm not sure my above understanding is ok. Please correct me if I'm wrong.

Thanks,
