Hello. The PHP ebuild doesn't support the multibyte string functions. According to the online manual, this option needs to be passed to configure: -enable-mbstring: Enable mbstring functions. This option is required to use mbstring functions I had a look at the ebuild, and couldn't find it. Also, 'equery uses dev-lang/php' lists a bunch of use flags, none of them related to mbstring. Perhaps adding (yet another) use flag to php so that we can have this and avoid errors like this: Fatal error: Call to undefined function mb_strtoupper() in /data/www/index.php on line 93

Sorry, I had 'unicode' USE flag enabled, but it seems I needed to restart apache. Should have thought about it.
