Even though there is a QT 3.2.1 ebuild in portage, there is not a matching qt-docs ebuild for that version number. Reproducible: Always Steps to Reproduce: none
It's okay, the new qt ebuilds take care of installing the docs themselves, based on if you have the doc use flag. qt docs isn't needed for the 3.2 version ebuilds.
good to know Caleb. Thanks. :)
