I just tested it in an overlay and it does its job nicely on amd64. Please flag it amd64 for all us thousands -- okay, three -- Gentoo HP Tablet PC users. Reproducible: Always Steps to Reproduce: 1. Flag it ~amd64, put in /etc/portage/package.keywords 2. emerge matchbox-keyboards 3. yay! Actual Results: It installed and worked. Note that it'll need to bring in libfakekey. Expected Results: It installed and worked.
Thanks for the report. Fixed in CVS.
