Well according to my failur(es) on gentoo:

Stumbled upon this when looking at the perl-gd xpm failure.
And surprise, it fails for a bunch of other perl packages as well.
We may be able to work around that, but really it would be a volatile
hack. I'm all for saving build time but fishing in the ocean with lake
kit... please no.

+1 for host-perl.

Regards.
