Re: [gentoo-alt] Re: 'Continuous Integration' for Gentoo Prefix?

[Fabian Groffen]

Hi Sam,

At this point I managed to get bootstrap to succeed on ppc-macos
(minority arch), I will continue with x64-macos and x64-solaris shortly.

I thought I fixed the Perl problem, aparently not.  I'll release a new
snapshot today/tomorrow, perhaps this brings some of the fixes forward.

Thanks,
Fabian
