I have march=pentium-m in my make.conf - will this get correctly
interpreted into i686 for the perl configure script?

The issue we had was that that DBI complained that it had missing
dependencies in the perl arch i686 tree6.  Looking at perl -V (emerged
from source) indicated that it had been built with arch=i386 and hence
modules lived under the i386 tree.

Resolved though.
Interestingly, re-emerging perl seems to have re-installed Perl correctly.

I'm still curious as to whether I can pass additional configure options
through emerge - I can imagine wanting to do so under other situations.
The one reference I've seen, seems to suggest editing the ebuild - which
seems like over kill.

Thanks for clarifying though.
