I think I'm going to change pcc to call addlocale instead of the internal setup as it works so well.
Tex, this is great news! OK, this is off-topic here but maybe, and because addlocale can also be used to restore to en_US, it should be re-named to Localization Manager
? In fact I already thought to also rename getopenoffice to OOmanager
for the same reasons (cause it installs, upgrades, adds locales, reinstalls, and properly removes OO).
just remembered that KDE4 does not support Malay but if you either install a different DE (i.e. task-gnome), or in case you already have a non-KDE version of PCLinuxOS installed, then you can use addlocale to add a Malay localization.
