Bugzilla Bug 178745

A quick check of app-portage/autounmask-0.15 for Bug 177238 stabilization
request shows this:
============================
autounmask --pretend =dev-lang/mono-1.2.3

 autounmask version 0.15 (using PortageXS-0.02.06)
 Bugs and requests go to ian <ian@gentoo.org>.

 * Using repositories:
     /usr/portage
     /usr/local/portage

 * Using package.keywords file: /etc/portage/package.keywords
 * Using package.unmask file: /etc/portage/package.unmask

 * Unmasking dev-lang/mono-1.2.3 and its dependencies.. this might take a
while..

 * Added '=dev-lang/mono-1.2.3 ~sparc64' to /etc/portage/package.keywords
 * Added '=dev-lang/mono-1.2.3' to /etc/portage/package.unmask
==============================================
But the correct keyword is just ~sparc, thus:
- dev-lang/mono-1.2.3 (masked by: ~sparc keyword)

ian@g.o is the maintainer :)

I suck. This error is fixed in dev-perl/PortageXS-0.02.07.

Thanks for bringing this to my attention! :)
